74LVC8T245 74LVCH8T245 8-bit dual supply translating transceiver 3-state Rev. 5 29 April 2021 Product data sheet 1. General description The 74LVC8T245 74LVCH8T245 are 8-bit dual supply translating transceivers with 3-state outputs that enable bidirectional level translation. They feature two data input-output ports (pins An and Bn), a direction control input (DIR), an output enable input (OE) and dual supply pins (V and CC(A) V ). Both V and V can be supplied at any voltage between 1.2 V and 5.5 V making CC(B) CC(A) CC(B) the device suitable 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 An, OE and DIR are referenced to V and pins Bn are referenced to CC(A) V . A HIGH on DIR allows transmission from An to Bn and a LOW on DIR allows transmission CC(B) from Bn to An. The output enable input (OE) can be used to disable the outputs so the buses are effectively isolated. 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 74LVCH8T245 holds unused or floating data inputs at a valid logic level. 2.
