74AVC4T245 4-bit dual supply translating transceiver with configurable voltage translation 3-state Rev. 7 29 April 2021 Product data sheet 1. General description The 74AVC4T245 is an 4-bit, dual supply transceiver that enables bidirectional level translation. The device can be used as two 2-bit transceivers or as a 4-bit transceiver. It features four 2-bit input-output ports (nAn and nBn), a direction control input (nDIR), a output enable input (nOE) and dual supply pins (V and V ). Both V and V can be supplied at any voltage CC(A) CC(B) CC(A) CC(B) 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 nAn, nOE and nDIR are referenced to V and pins nBn are referenced to V . A HIGH on nDIR allows transmission from nAn to CC(A) CC(B) nBn and a LOW on nDIR allows transmission from nBn to nAn. The output enable input (nOE) 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 nAn and nBn CC(A) CC(B) are in the high-impedance OFF-state. 2.
