NXU0x04電壓位準轉換緩衝區

Nexperia NXU0x04 Voltage-Level Translating Buffers are 4-bit, dual-supply level translating buffers with 3-state outputs. These buffers feature four data inputs, four data outputs, and an output enable input. V_CCA and V_CCB can be supplied at any voltage between 0.9V and 5.5V, making the devices suitable for translating between any voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V). The Nexperia NXU0x04 devices facilitate asynchronous communication between data buses. These buffers transmit data in a fixed direction (unidirectionally) from the A bus to the B bus on four channels. The OE pin can be referenced to the V_CCA and V_CCB domains, and when the OE pin is set to LOW, the output is disabled and enters a high-impedance OFF state, which isolates the buses. The OE pin can be left floating or externally pulled down to the ground to ensure the high-impedance state of the output during power up/down.
