SEMICONDUCTOR TECHNICAL DATA

The MC74LCX16543 is a high performance, non–inverting 16–bit

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

byte controlled. Each byte has separate control 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 compatible

LOW–VOLTAGE CMOS

16–BIT LATCHING

TRANSCEIVER

outputs offer improved switching noise performance. A V specification of

5.5V allows MC74LCX16543 inputs to be safely driven from 5V devices.

The MC74LCX16543 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 latches, and the outputs no longer change with the A

inputs. With EAB and OEAB both LOW, the 3–State B output buffers are

active and reflect the data present at the output of the A latches. Control

of data flow from B to A is symetric to that above, but uses the EBA,

LEBA, and OEBA inputs.
