74AVC1T45 Dual-supply voltage level translator/transceiver 3-state Rev. 9 6 July 2021 Product data sheet 1. General description The 74AVC1T45 is a single bit, dual supply transceiver with 3-state output that enables bidirectional level translation. It features two 1-bit input-output ports (A and B), a direction control input (DIR) and dual supply pins (V and V ). Both V and V can be supplied at any CC(A) CC(B) CC(A) CC(B) voltage between 0.8 V and 3.6 V making the device suitable for translating between any of the low voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V). Pins A and DIR are referenced to V CC(A) and pin B is referenced to V . A HIGH on DIR allows transmission from A to B and a LOW on CC(B) DIR allows transmission from B to A. The device is fully specified for partial power-down applications using I . The I circuitry OFF OFF disables the output, preventing any damaging backflow current through the device when it is powered down. In suspend mode when either V or V are at GND level, both A and B are CC(A) CC(B) in the high-impedance OFF-state. 2.
