74LVC2T45 74LVCH2T45 Dual supply translating transceiver 3-state Rev. 11 16 September 2021 Product data sheet 1. General description The 74LVC2T45 74LVCH2T45 are dual bit, dual supply translating transceivers with 3-state outputs that enable bidirectional level translation. They feature two 2-bits input-output ports (nA and nB), a direction control input (DIR) and dual supply pins (V and V ). Both V CC(A) CC(B) CC(A) and V can be supplied at any voltage between 1.2 V and 5.5 V making the device suitable CC(B) for translating between any of the low voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V). Pins nA and DIR are referenced to V and pins nB are referenced to V . A HIGH on DIR CC(A) CC(B) allows transmission from nA to nB and a LOW on DIR allows transmission from nB to nA. The devices are 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 port and CC(A) CC(B) B port are in the high-impedance OFF-state. Active bus hold circuitry in the 74LVCH2T45 holds unused or floating data inputs at a valid logic level. 2.
