1. General description

The NXB0108 is an 8-bit, dual supply translating transceiver with auto direction sensing, that

enables bidirectional voltage level translation. It features two 8-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.
