1. General description

The NXB0102-Q100 is a 2-bit, dual supply translating transceiver with auto direction sensing, that

enables bidirectional voltage level translation. It features two 2-bit input-output ports (An and Bn),

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). Pins An and OE are referenced to VCC(A) and pins Bn are

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.
