74AVCH4T245 4-bit dual supply translating transceiver with configurable voltage translation 3-state Rev. 5 17 December 2015 Product data sheet 1. General description The 74AVCH4T245 is a 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 two 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 CC(A) CC(B) CC(A) V can be supplied at any voltage between 0.8 V and 3.6 V making the device suitable CC(B) 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 CC(A) V . A HIGH on nDIR allows transmission from nAn to nBn and a LOW on nDIR allows CC(B) 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 OFF OFF circuitry 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 CC(A) CC(B) GND level, both nAn and nBn outputs are in the high-impedance OFF-state. The bus hold circuitry on the powered-up side always stays active. The 74AVCH4T245 has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors. 2.
