74AVC2T45 Dual-bit, dual-supply voltage level translator/transceiver 3-state Rev. 10 4 November 2021 Product data sheet 1. General description The 74AVC2T45 is a dual-bit, dual-supply transceiver that enables bidirectional level translation. It features two data input-output ports (nA and nB), a direction control input (DIR) and dual-supply pins (V and V ). Both V and V can be supplied at any voltage between 0.8 V CC(A) CC(B) CC(A) CC(B) 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 nA and DIR are referenced to V and pins nB CC(A) are referenced to V . A HIGH on DIR allows transmission from nA to nB and a LOW on DIR CC(B) allows transmission from nB to nA. 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.
