1. General description
The NXS0104 is a 4-bit, dual supply translating transceiver with auto direction sensing, that
enables bidirectional voltage level translation. It features two 4-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.
