1. General description
The NVT2001/02 are bi directional volt age level transla tors operational fro m 1.0 V to 3.6 V
(Vref(A)) and 1.8 V to 5.5 V (Vref(B)), which allow bidirectional voltage translations be tween
1.0 V and 5 V without the need for a direction pin in open-drain or push -pull applications.
Bit widths ranging from 1-bit or 2-bit are offered for level translation application with
transmission speeds < 33 MHz for an open-drain system with a 50 pF capacitance and a
pull-up of 197 .
When the An or Bn port is LOW, the clamp is in the ON-state and a low resistance
connection exists between the An and Bn ports. The low ON-state resistance (Ron) of the
switch allows connections to be made with minimal propagation delay. Assuming the
higher voltage is on the Bn port when the Bn port is HIGH, the voltage on the An port is
limited to the voltage set by VREF A. When the An port is HIGH, the Bn port is pulled to the
drain pull-up supply voltage (Vpu(D)) by the pull-up resistors. This functionality allows a
seamless translation between higher and lower voltages selected by the user witho ut the
need for directional control.
When EN is HIGH, the translator switch is on, and the An I/O are connected to the Bn I/O,
respectively, allowing bidirectional data flow between ports. When EN is LOW, the
translator switch is off, and a high-impe dance state exists between ports. The EN input
circuit is designed to be supplied by Vref(B). To ensure the high-impedanc e state during
power-up or power-down, EN must be LOW.
All channels have the same electrical characteristics and there is minimal deviation from
one output to another in voltage or propagation delay. This is a benefit over discrete
transistor voltage translation solutions, since the fabrication of the switch is symmetrical.
The translator provides excellent ESD protection to lower voltage devices, and at the
same time protects less ESD-resistant devices.

7. Application design-in information
The NVT2001/02 can be used in level translation applications for interfacing devices or
systems operating at different interface voltages with one another. The NVT2001/02 is
ideal for use in applications whe re an open-dra in driver is conne cted to the dat a I/Os. The
NVT2001/02 can also be used in applica tions where a push-pu ll driver is connected to the
data I/Os.
7.1 Enable and disable
The NVT20xx has an EN input that is used to disable the device by setting EN LOW,
which places all I/Os in the high-impedance state.
[1] All typical values are at Tamb =25C.
(1) The applied voltages at Vref(A) and Vpu(D) should be such that Vref(B) is at least 1 V higher than

Bidirectional voltage level translator
7.2 Bidirectional translation
For the bidirectional clamping configuration (higher volt age to lower voltage or lower
voltage to h igher voltage), the EN input m ust be connected to VREFB and both pins pulled
to HIGH side Vpu(D) through a pull-up resistor (typically 200 k). This allows VREFB to
regulate the EN input. A filter capacitor on VREFB is recommended. The master output
driver can be totem pole or open-drain (pull-up resistors may be required) and the slave
device output can b e totem pole or open-drain (pu ll-up resistors are requ ired to pull the Bn
outputs to Vpu(D)). However, if either output is totem-pole, data must be unidirectional or
the outputs must be 3-stateable and be controlled by some direction-control mechanism
to prevent HIGH-to-LOW contentions in either dire ction. If both output s ar e open-drain, n o
direction control is needed.
The reference supply voltage (Vref(A)) is connected to the processor core power supply
voltage. When VREFB is connected through a 200 k resistor to a 3.3 V to 5.5 V Vpu(D)
power supply, and Vref(A) is set between 1.0 V and (Vpu(D) 1 V), the output of ea ch An
has a maximum output voltage equal to VREFA, and the output of each Bn has a
maximum output voltage equal to Vpu(D).
7.3 Sizing pull-up resistor
The pull-up resistor value needs to limit the current through the pass transistor when it is
in the ON state to about 15 mA. This ensures a pass voltage of 260 mV to 350 mV. If the
current through the p ass transistor is higher than 15 mA, the pass volt age also is higher in
the ON state. To set the curre nt through each pass transistor at 15 mA, the pull-up resistor
value is calculated as:
Table 5 summarizes resistor reference voltages and currents at 15 mA, 10 mA, and 3 mA.
The resistor values shown in the +10 % column or a larger value should be used to
ensure that the p ass voltage of the tra nsistor would be 350 mV or less. The external driver
must be able to sink the total current from the resistors on both sides of the NVT20xx
device at 0.175 V, althou g h th e 15 mA only applies to current flowing through the
NVT20xx device.

7.3.1 Maximum frequency calculation
The maximum freq uency is tota lly dependent u pon the sp ecifics of the application and the
device can operate > 33 MHz. Basically, the NVT20xx behaves like a wire with the
additional characte ristics of transistor device physics and should be capable of performing
at higher frequencies if used correctly.
Here are some guidelines to follow that will help maximize the performance of the device:
Keep trace length to a minimum by placing the NVT20xx close to the processor.
The trace length should have a time of flight less than half of the transition time to
reduce ringing an d re fle ctio n s .
The faster the edge of the signal, the higher the chance for ringing.
The higher the drive strength (up to 15 mA), the higher the frequency the device can
use.
In a 3.3 V to 1.8 V direction level shift, if the 3.3 V side is being driven by a totem pole type
driver no pull-up resistor is needed on the 3.3 V side. The capacitance and line length of
concern is on the 1.8 V side since it is driven through the ON resistance of the NVT20xx.
If the line length on the 1.8 V side is long enough there can be a reflection at the
chip/terminating end of the wir e when the transition time is shorter than the time of flight of
the wire because the NVT20xx looks like a high-impedance compared to the wire. If the
wire is not too long and the lumped capacitance is not excessive the signal will only be
slightly degraded by the series resistance added by passing through the NVT20xx. If the
lumped capacitance is large the rise time will deteriorate, the fall time is much less
affected and if the rise time is slowed down too much the duty cycle of the clock will be
degraded and at some point the clock will no longer be useful. So the principle design
consideration is to minimize the wire length and the capacitance on the 1.8 V side fo r the
clock path. A pull-u p resistor on the 1.8 V side can also be used to tr ade a slower fall tim e
for a faster rise time and can also reduce the overshoot in some cases.
7.3.1.1 Example maximum frequency
Question — W e need to make the PL L area of a new line card backwards comp atible and
need to need to convert one GTL signal to LVTTL, invert it, and convert it back to GTL.
The signal we want to convert is random in nature but will mostly be around 19 MHz with
very long periods of inactivity where either a HIGH or LOW state will be maintained. The
traces are 1 or 2 inches lon g with tra ce capacitance of about 2 pF pe r inch .
Answer — The frequency of the NVT20xx is limited by the capacitance of the part, the
capacitance of the traces and the pull-u p resistors used. The limiting ca se is pr obably th e
LOW-to-HIGH transition in the GTL to LVTTL direction, and there the use of the lowest
acceptable resistor values will minimize the rise time delay. Assuming 50 pF capacitance
and 220 resistance, the RC time constant is 11 ns (50 pF 220 ). With 19 MHz
corresponding to 50 ns period the NVT20xx will support this application.

12. Performance curves
tPLH up-translation is typically dominated by the RC time constant, i.e.,
CL(tot) RPU =50pF197 = 9.85 ns, but the Ron CL(tot) =50pF5=0.250ns.
tPHL is typically domina te d by the external pull-d o wn dr ive r + Ron, which is typically small
compared to the tPLH in an up-translation case.
Enable/disable times are dominated by the RC time constant on the EN pin since the
transistor turn off is on the order of ns, but the enable RC is on the order of ms.
Fall time is dominated by the external pull-down driver with only a slight Ron addition.
Rise time is dominated by the RPU CL.
Skew time within the part is virtually non-existent, dominated by the difference in bond
wire lengths, which is typically small compared to the board-level ro uting differences.
Maximum data rate is dominated by the system cap acitance and pull-up resistors.

14. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
14.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
14.2 Wave and reflow soldering
W ave soldering is a joinin g technology in which the joint s are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
Through-hole components
Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
Board specifications, including the board finish, solder masks and vias
Package footprints, including solder thieves and orientation
The moisture sensitivity level of the packages
Package placement
Inspection and repair
Lead-free soldering versus SnPb soldering
14.3 Wave soldering
Key characteristics in wave soldering are:
Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
Solder bath specifications, including temperature and impurities

14.4 Reflow soldering
Key characteristics in reflow soldering are:
Lead-free ve rsus SnPb soldering; note th at a lead-free reflow process usua lly leads to
higher minimum peak temperatures (see Figure 18) than a SnPb process, thus
reducing the process window
Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enoug h for the solder to make reliable solder joint s (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 10 and 11
Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 18.
