General description

The NTS0102 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 1.65 V and 3.6 V and VCC(B)

can be supplied at any voltage between 2.3 V and 5.5 V, making 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 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.
