Description

General part information

SN74AVCAH164245 Series

This 16-bit (dual-octal) noninverting bus transceiver uses two separate configurable power-supply rails. The A-port is designed to track VCCA. VCCAaccepts any supply voltage from 1.4 V to 3.6 V. The B-port is designed to track VCCB. VCCBaccepts any supply voltage from 1.4 V to 3.6 V. This allows for universal low-voltage bidirectional translation between any of the 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

The SN74AVCAH164245 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 the buses are effectively isolated.

The SN74AVCAH164245 is designed so that the control pins (1DIR, 2DIR, 1OE\, and 2OE\) are supplied by VCCA.
