Description

General part information

SN74AVCH20T245 Series

This 20-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74AVCH20T245 is optimized to operate with VCCA/VCCBset at 1.4 V to 3.6 V. It is operational with VCCA/VCCBas low as 1.2 V. The A port is designed to track VCCA. VCCAaccepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCBaccepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

The SN74AVCH20T245 is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE)\ input can be used to disable the outputs so that the buses are effectively isolated.

The SN74AVCH20T245 is designed so that the control (1DIR, 2DIR, 1OE\, and 2OE\) inputs are supplied by VCCA.
