SEMICONDUCTOR TECHNICAL DATA

The MC74LCX16245 is a high performance, non–inverting 16–bit

transceiver operating from a 2.7 to 3.6V supply. The device is byte

controlled. Each byte has separate Output Enable inputs which can be

tied together for full 16–bit operation. High impedance TTL compatible

inputs significantly reduce current loading to input drivers while TTL

LOW–VOLTAGE

compatible outputs offer improved switching noise performance. A V

CMOS 16–BIT TRANSCEIVER

specification of 5.5V allows MC74LCX16245 inputs to be safely driven

from 5V devices. The MC74LCX16245 is suitable for memory address

driving and all TTL level bus oriented transceiver applications.

4.5ns maximum propagation delays support high performance

applications. Current drive capability is 24mA at both A and B ports. The

Transmit/Receive (T/Rn) inputs determine the direction of data flow

through the bi–directional transceiver. Transmit (active–HIGH) enables

data from A ports to B ports; Receive (active–LOW) enables data from B

to A ports. The Output Enable inputs (OEn), when HIGH, disable both A

and B ports by placing them in a HIGH Z condition.
