74AVC8T245 8-bit dual supply translating transceiver with configurable voltage translation 3-state Rev. 7 29 April 2021 Product data sheet 1. General description The 74AVC8T245 is an 8-bit, dual supply transceiver that enables bidirectional level translation. It features two 8-bit input-output ports (An and Bn), a direction control input (DIR), a output enable input (OE) 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 An, OE and DIR are referenced to V and pins Bn are referenced to V . A HIGH on DIR allows transmission from An to Bn and CC(A) CC(B) a LOW on DIR allows transmission from Bn to An. The output enable input (OE) can be used to disable the outputs so the buses are effectively isolated. 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 An and Bn CC(A) CC(B) are in the high-impedance OFF-state. 2.
