Overview

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information Low-Voltage CMOS Octal Latching Transceiver With 5V-Tolerant Inputs and Outputs (3-State, Non-Inverting) MC74LCX543 The MC74LCX543 is a high performance, non–inverting octal latching transceiver operating from a 2.
7 to 3.
6V supply.
High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance.
A VI specification of 5.
5V allows MC74LCX543 inputs to be safely driven from 5V devices.
The MC74LCX543 is suitable for memory address driving and all TTL level bus oriented transceiver applications.
For data flow from A to B with the EAB LOW, the A–to–B Output Enable (OEAB) must be LOW in order to enable data to the B bus, as indicated in the Function Table.
With EAB LOW, a LOW signal on the A–to–B Latch Enable (LEAB) input makes the A–to–B latches transparent; a subsequent LOW–to–HIGH transition of the LEAB signal will latch the A lat...
