General description

The NTS0103 is a 3-bit, dual supply translating transceiver with auto direction sensing,

that enables bidirectional voltage level translation. It features two 3-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.
