General Description
The MAX3394E/MAX3395E/MAX3396E bidirectional
level translators provide level shifting required for data
transfer in a multivoltage system. Internal slew-rate
enhancement circuitry features 10mA current-sink and
15mA current-source drivers to isolate capacitive loads
from lower current drivers. In open-drain systems, slew-
rate enhancement enables fast data rates with larger
pullup resistors and increased bus load capacitance.
Externally applied voltages, VCC and VL, set the logic-
high levels for the device. A logic-low signal on one I/O
side of the device appears as a logic-low signal on the
opposite I/O side, and vice-versa. Each I/O line is
pulled up to VCC or VLby an internal pullup resistor,
allowing the devices to be driven by either push-pull or
open-drain drivers.
The MAX3394E/MAX3395E/MAX3396E feature a tri-
state output mode, thermal-shutdown protection, and
±15kV Human Body Model (HBM) ESD protection on
the VCC side for greater protection in applications that
route signals externally.
The MAX3394E/MAX3395E/MAX3396E accept VCC volt-
ages from +1.65V to +5.5V, and VLvoltages from +1.2V
to VCC, making them ideal for data transfer between low
voltage ASIC/PLDs and higher voltage systems. The
MAX3394E/MAX3395E/MAX3396E operate at a guaran-
teed data rate of 6Mbps with push-pull drivers and
1Mbps with open-drain drivers.
The MAX3394E is a dual-level translator available in
9-bump UCSP™ and 8-pin 3mm x 3mm TDFN packages.
The MAX3395E is a quad-level translator available in 12-
bump UCSP, and 12-pin 4mm x 4mm TQFN packages.
The MAX3396E is an octal-level translator available in 20-
bump UCSP and 20-pin 5mm x 5mm TQFN packages.
The MAX3394E/MAX3395E/MAX3396E operate over the
extended -40°C to +85°C temperature range.

Note 1: All units are 100% production tested at TA= +25°C. Limits over the operating temperature range are guaranteed by design
and not production tested.
Note 2: During a low-to-high transition, the threshold at which the I/O changes state is the lower of VILL and VILC since the two sides
are internally connected by an internal switch while the device is in the logic-low state.

MAX3394E/MAX3395E/MAX3396E
The MAX3394E/MAX3395E/MAX3396E feature a tri-
state output mode, thermal-shutdown protection, and
±15kV Human Body Model (HBM) ESD protection on
the VCC side for greater protection in applications that
route signals externally.
The MAX3394E/MAX3395E/MAX3396E accept VCC volt-
ages from +1.65V to +5.5V, and VLvoltages from +1.2V
to VCC, making them ideal for data transfer between low-
voltage ASIC/PLDs and higher voltage systems. The
MAX3394E/MAX3395E/MAX3396E operate at a guaran-
teed data rate of 6Mbps with push-pull drivers and
1Mbps with open-drain drivers.
Level Translation
The MAX3394E/MAX3395E/MAX3396E utilize a trans-
mission gate architecture to provide bidirectional level
translation between I/O VL_ and I/O VCC_. The trans-
mission gate architecture is comprised of a pass-FET,
gate-control logic, and slew-rate enhancement circuit-
ry. When both I/O VL_ and I/O VCC_ are logic high, the
gate-control logic disables the pass-FET, providing
±15kV ESD-Protected, High-Drive Current, Dual-/Quad-/
Octal-Level Translators with Speed-Up Circuitry

logic turns the pass-FET on. When the pass-FET is
active, I/O VL_ and I/O VCC_ are connected, allowing
the logic-low signal to be expressed simultaneously on
both I/O lines.
The MAX3394E/MAX3395E/MAX3396E have internal
10kΩ(typ) pullup resistors from I/O VL_ and I/O VCC_
to the respective supply voltages, allowing operation
with open-drain drivers. Internal slew-rate enhancement
circuitry accelerates logic-state transitions, maintaining
a fast data rate with a higher bus load capacitance.
Additionally, the 10mA current sink drivers permit the
use of smaller external pullup resistors.
Internal Slew-Rate Enhancement
Internal slew-rate enhancement circuitry accelerates
logic-state changes by turning on MOSFETs MP1 and
MP2 during low-to-high logic transitions, and MOSFETs
MN3 and MN4 during high-to-low logic transitions (see
the Functional Diagram). During logic-state changes,
speed-up MOSFETS are triggered by I/O line voltage
thresholds. MOSFETS MN3 and MN4 sink 10mA during
high-to-low logic transitions. MP1 and MP2 source 15mA
during low-to-high logic transitions. Slew-rate enhance-
ment allows a fast data rate despite large capacitive bus
loads, and permits larger external pullup resistors.

Power-Supply Sequencing
The MAX3394E/MAX3395E/MAX3396E require two sup-
ply voltages. For proper operation, ensure that +1.65V ≤
VCC ≤+5.5V, and +1.2V ≤VL≤VCC. There are no restric-
tions on power-supply sequencing. During power-up or
power-down, the MAX3394E/MAX3395E/MAX3396E can
withstand either the VLor the VCC supply floating while
the other supply is applied. The device will not latch up in
this state.
Tri-State Output Mode
Connect EN to VLor VCC for normal operation. Drive
EN low to force the MAX3394E/MAX3395E/MAX3396E
to a tri-state output mode. In tri-state output mode, all
I/O lines are driven to a high-impedance state, and the
pass-FET is disabled to prevent current flow between
I/O lines. Tri-state output mode disables the internal
pullup resistors on I/O VL_ and I/O VCC_, and reduces
supply current to 3µA typ (VCC) and 0.7µA typ (VL).

The high-impedance state of the I/O lines during tri-
state output mode facilitates use in multidrop networks.
In tri-state output mode, do not exceed (VL+ 0.3V) on
I/O VL_ or (VCC + 0.3V) on I/O VCC_.
Thermal-Shutdown Protection
The MAX3394E/MAX3395E/MAX3396E are protected
from thermal damage resulting from short-circuit faults.
In the event of a short-circuit fault, when the junction
temperature (TJ) reaches +125°C, a thermal sensor
forces the device into the tri-state output mode. When
TJdrops below +115°C, normal operation resumes.
±15kV ESD Protection
As with all Maxim devices, ESD-protection structures are
incorporated on all pins to protect against ESD encoun-
tered during handling and assembly. The I/O VCC_ lines
are further protected by advanced ESD structures to
guard these pins from damage caused by ESD of up to
±15kV. Protection structures prevent damage caused by
ESD events in normal operation, tri-state output mode,
and when the device is unpowered. After arresting an
ESD event, MAX3394E/MAX3395E/MAX3396E continue
to function without latching up, whereas competing
devices can enter a latched-up state and must be power
cycled to restore functionality.
Several ESD testing standards exist for gauging the
robustness of ESD structures. The ESD protection of
the MAX3394E/MAX3395E/MAX3396E is characterized
for the human body model (HBM). Figure 6a shows the
model used to simulate an ESD event resulting from
contact with the human body. The model consists of a
100pF storage capacitor that is charged to a high volt-
age then discharged through a 1.5kΩresistor. Figure
6b shows the current waveform when the storage
capacitor is discharged into a low impedance.
To ensure full ±15kV ESD protection, bypass VCC to
ground with a 0.1µF ceramic capacitor and an additional
1µF ceramic capacitor as close to the device as possible.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report documenting test
setup, methodology, and results.
Applications Information
Power-Supply Decoupling
Bypass VLand VCC to ground with 0.1µF ceramic
capacitors. To ensure full ±15kV ESD protection,
bypass VCC to ground with an additional 1µF or greater
ceramic capacitor. Place all capacitors as close to the
device as possible.
Open-Drain Mode vs. Push-Pull Mode
The MAX3394E/MAX3395E/MAX3396E are compatible
with push-pull (active) and open-drain drivers. For push-
pull operation, maximum data rate is guaranteed to
6Mbps. For open-drain applications, the MAX3394E/
MAX3395E/MAX3396E include internal pullup resistors
and slew-rate enhancement circuitry, providing a maxi-
mum data rate of 1Mbps. External pullup resistors can
be added to increase data rate when the bus is loaded
by high capacitance. (See the Use of External Pullup
Resistors section.)
Serial-Interface Level Translation
The MAX3395E provides level translation on four I/O
lines, making it an ideal device for multivoltage I2C,
MICROWIRE, and SPI serial interfaces.
Use of External Pullup Resistors
The MAX3394E/MAX3395E/MAX3396E include internal
10kΩpullup resistors. During a low-to-high logic transi-
tion, the internal pullup resistors charge the bus capac-
itance with a characteristic RC charging waveform.

Functional Diagram
When the low-to-high transition threshold (VCC-TH or VL-
TH) is reached, the rise time accelerators switch on,
sourcing 15mA to fully charge the bus capacitance.
External pullup resistors reduce the time needed to
reach the low-to-high transition threshold, thereby
increasing the data rate. In the logic-low state however,
external pullup resistors increase the DC current
through the internal pass-FET, increasing the output
voltage of the device.
Smart-Card Interface
The MAX3395E provides level translation for Class A, B,
and C smart cards. When supply voltage VCC is inter-
rupted due to the disconnection of a smart card, the
device does not latch up. Normal operation resumes
upon restoration of the VCC supply voltage. The
MAX3395E provides bidirectional level translation on
four I/O lines, making it well suited for buffering and
translating 4-wire serial interfaces.
