74AVCH16T245 16-bit dual supply translating transceiver with configurable voltage translation 3-state Rev. 5 1 March 2012 Product data sheet 1. General description The 74AVCH16T245 is a 16-bit transceiver with bidirectional level voltage translation and 3-state outputs.The device can be used as two 8-bit transceivers or as a 16-bit transceiver. It has dual supplies (V and V ) for voltage translation and four 8-bit CC(A) CC(B) input-output ports (nAn, nBn) each with its own output enable (nOE) and send/receive (nDIR) input for direction control. V and V can be independently supplied at any CC(A) CC(B) voltage between 0.8 V and 3.6 V making the device suitable for low voltage translation between any of the following voltages: 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V. A HIGH on nDIR selects transmission from nAn to nBn while a LOW on nDIR selects transmission from nBn to nAn. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state 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 A and B outputs are in the high-impedance OFF-state. The bus-hold circuitry on the powered-up side always stays active. The 74AVCH16T245 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.
