74AVC1T45GW (NEXPERIA)

The 74AVC1T45GW is a single-bit dual supply Voltage Level Translator/Transceiver with 3-state output that enables bidirectional level translation. It features two 1-bit input-output ports, a direction control input and dual supply pins. Both VCC(A) and VCC(B) can be supplied at any voltage between 0.8 and 3.6V making the device suitable for translating between any of the low voltage nodes. Pins A and DIR are referenced to VCC(A) and pin B is referenced to VCC(B). A HIGH on DIR allows transmission from A to B and a LOW on DIR allows transmission from B to A. The device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when either VCC(A) or VCC(B) are at GND level, both A and B are in the high-impedance OFF-state.
