The NXU0102-Q100 is a 2-bit, dual-supply level translating buffer with Schmitt-trigger inputs and 3-state outputs. It features two data inputs (A1 and A2), two data outputs (YB1 and YB2), and an output enable input (OE).
Both VCCA and VCCB can be supplied at any voltage between 0.9 V and 5.5 V making the device suitable for translating between any of the voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V).
This device facilitates asynchronous communication between data buses. Transmit data with a fixed direction (unidirectionally) from the A bus to the B bus on two channels. The OE pin can be referenced to VCCA and VCCB domain and when OE pin is set LOW the outputs are disabled and enter a high-impedance OFF-state which isolates the buses. The OE pin can be left floating or externally pulled down to ground to ensure the high-impedance state of the outputs during power up or power down.
This device ensures low static and dynamic power consumption across the entire supply range and is fully specified for partial power down applications using IOFF. The IOFF circuitry prevents potentially damaging backflow current through the device when it is powered down or if one of the power supplies is disconnected (floating).
No power supply sequencing is required and output glitches during power supply transitions are prevented. As a result, glitches will not appear on the outputs for supply transitions during power-up/down.
