BIDIRECTIONAL

TRANSCEIVER

DESCRIPTION:

The FCT162245T 16-bit transceiver is built using advanced dual metal

CMOS technology. These high-speed, low-power transceivers are ideal for

synchronous communication between two buses (A and B). The Direction and

Output Enable controls operate these devices as either two independent 8-bit

transceivers or one 16-bit transceiver. The direction control pin (xDIR) controls

the direction of data flow. The output enable pin (xOE) overrides the direction

control and disables both ports. All inputs are designed with hysteresis for

improved noise margin.

The FCT162245T has balanced output drive with current limiting resistors.

This offers low ground bounce, minimal undershoot, and controlled output fall

times–reducing the need for external series terminating resistors. The

FCT162245T is a plug-in replacement for the FCT16245T and ABT16245 for

on-board interface applications.
