1. General description

2. Features and benefits

The 74AVC20T245 is a 20-bit, dual supply transceiver that enables bi-directional voltage

level translation. The device can be used as two 10-bit transceivers or as a single 20-bit

transceiver. It features four 10-bit input-output ports (1An, 1Bn and 2An, 2Bn), two output

enable inputs (nOE), two direction inputs (nDIR) and dual supplies (V

making the device suitable for bi-directional voltage level translation 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. The 1An and 2An ports, nOE

and nDIR are referenced to V

HIGH on a 1DIR allows transmission from 1An to 1Bn and a LOW on 1DIR allows

transmission from 1Bn to 1An. 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

circuitry disables the output, preventing any damaging backflow current through the

device when it is powered down. In suspend mode when either V

GND level, all output ports will assume a high impedance OFF-state.
