General description

The NTSX2102 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)).

Both supplies can be supplied at any voltage between 1.65 V and 5.5 V. This flexibility

makes the device suitable for translating between any of the voltage nodes (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 OFFstate.

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.
