SEMICONDUCTOR TECHNICAL DATA

J SUFFIX

CERAMIC PACKAGE

CASE 732–03

High–Performance Silicon–Gate CMOS

The MC54/74HC244A is identical in pinout to the LS244. The device

inputs are compatible with standard CMOS outputs; with pullup resistors,

they are compatible with LSTTL outputs.

This octal noninverting buffer/line driver/line receiver is designed to be

used with 3–state memory address drivers, clock drivers, and other

bus–oriented systems. The device has noninverting outputs and two

active–low output enables.
