1. General description
The NTB0101 is a 1-bit, dual supply translating transceiver with auto direction sensing,
that enables bidirectional voltage level translation. It features two 1-bit input-output ports
(A and B), one output enable input (OE) and two supply pins (VCC(A) and VCC(B)). VCC(A)
can be supplied at any voltage betwee n 1.2 V and 3.6 V and V CC(B) can be supplied at any
voltage be tween 1.65 V and 5.5 V, making the device suit able for translating between any
of the low voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V).
Pins A and OE are referenced to VCC(A) and pin B is referenced to VCC(B). A LOW level at
pin OE causes the outputs to assume a high-impedance OFF -s tate. This device is fully
specified for partial power-down applications using IOFF. The IOFF circuitry disables the
output, prev en tin g the da m ag i ng ba ckflo w cu rr ent through the device when it is powered
down.
2. Features and benefits
Wide supply voltage range:
VCC(A): 1.2 V to 3.6 V and VCC(B): 1.65 V to 5.5 V
IOFF circuitry provides partial Power-down mode operation
Inputs accept voltages up to 5.5 V
ESD protection:
HBM JESD22-A114E Class 2 exceeds 2500 V for A port
HBM JESD22-A114E Class 3B exceeds 15000 V for B port
MM JESD22-A115-A exce ed s 200 V

13.2 Architecture
The architecture of the NTB0101 is shown in Figure 9. The device does no t require an
extra input signal to control the dir ection of dat a flow fr om A to B or from B to A. In a st a tic
state, the output drivers of the NTB0101 can maintain a defined output level, but the
output architecture is designed to be weak, so that they can be overdriven by an external
driver when dat a on the bus st arts flowing in the opposite direction. Th e output of one-shot
circuits detect rising or falling edges on the A or B ports. During a rising edge, the
one-shot circuits turn on the PMOS transistors (T1, T3) for a short duration, acceler ating
the LOW-to-HIGH transition. Similarly, during a falling edge, the one-shot circuits turn on
the NMOS transistors (T2, T4) for a short duration, accelerating the HIGH-to-LOW
transition. During output transitions the typical output impedance is 70 at VCCO = 1.2 V
to 1.8 V, 50 at VCCO = 1.8 V to 3.3 V and 40 at VCCO = 3.3 V to 5.0 V.

13.3 Input driver requirements
For correct operation, the device driving the data I/Os of the NTB0101 must have a
minimum drive capability of 2 mA See Figure 10 for a plot of typical input current versus
input voltage.
13.4 Power-up
During operation VCC(A) must never be higher than VCC(B), however during power- up
VCC(A) VCC(B) does not damage the device, so ei ther power supply can be ramped up
first. There is no special power-up sequencing required. The NTB0101 includes circuitry
that disables all output ports when either VCC(A) or VCC(B) is switched off.
13.5 Enable and disable
An output enable input (OE) is used to disable the device. Setting OE = LOW causes all
I/Os to assume the high-impedance OFF-state. The disable time (tdis with no external
load) indicates the delay between when OE goes LOW and when outputs actually
become disabled. The enable time (ten) indicates the amount of time the user must allow
for one one-shot circuitry to become operational after OE is taken HIGH. To ensure the
high-impedance OFF-state during power-up or power-down, pin OE should be tied to
GND through a pull-down resisto r, the minimum value of the resisto r is determin ed b y the
current-sourcing capability of the driver.
13.6 Pull-up or pull-down resistors on I/O lines
As mentioned previously the NTB0101 is designed with low static drive strength to drive
capacitive loads of up to 70 pF. To avoid output contention issues, any pull-up or
pull-down resistors used must be above 50 k. For this reason the NTB0101 is not
recommended for use in open drain driver applications such as 1-Wire or I2C-bus. For
these applicat ion s , the NT S01 0 1 leve l tra ns lat or is reco mm e nde d.
VT: input threshold voltage of the NTB0101 (typically VCCI / 2).
VD: supply voltage of the external driver.
