1. General description

The NXB0101-Q100 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 between 1.2 V and 3.6 V and VCC(B) can be supplied at any voltage between 1.65 V and

5.5 V, making the device suitable 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). Pin A and OE are referenced to VCC(A) and pins B is referenced to

VCC(B). A LOW level at pin OE causes the outputs to assume a high-impedance OFF-state. This

device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables

the output, preventing the damaging backflow current through the device when it is powered down.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
