Nexperia NXU0204BQX

NXU0204 is a 4-bit dual-supply level-translating buffer with Schmitt-trigger inputs and 3-state outputs. It features four data inputs (A1, A2, B3, and B4), four data outputs (YB1, YB2, YA3, and YA4), and one output enable input (OE). Both VCCA and VCCB support any supply voltage between 0.9 V and 5.5 V, making the device suitable for translation between any voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V). The device facilitates asynchronous communication between data buses. Data is transferred in a fixed direction (unidirectional) — from the A bus to the B bus on three channels, and from the B bus to the A bus on one channel. The OE pin can be referenced to either the VCCA or VCCB domain. When the OE pin is driven LOW, the outputs are disabled and enter a high-impedance off state, thereby isolating the buses. The OE pin can be left floating or externally pulled down to GND to ensure the outputs remain in a high-impedance state during power-up or power-down. The device ensures low quiescent and dynamic power consumption across the full supply voltage range, and is fully specified for partial power-down applications using IOFF. The IOFF circuitry prevents potentially damaging reverse current from flowing through the device when the device is powered down or either supply is disconnected (floating). No power supply sequencing is required, and output glitches during power supply transitions are prevented. As a result, no glitches appear at the outputs during power supply transitions in power-up/power-down sequences.
