General description
The NTS0102-Q100 is a 2-bit, dual supply translating transceiver with auto direction
sensing, that enables bidirectional voltage level translation. It features two 2-bit inputoutput
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. This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
