MC74HCT541A

Octal 3-State Non-Inverting

Buffer/Line Driver/

Line Receiver With

LSTTL-Compatible Inputs

High−Performance Silicon−Gate CMOS

The MC74HCT541A is identical in pinout to the LS541. This

device may be used as a level converter for interfacing TTL or NMOS

outputs to high speed CMOS inputs.

The HCT541A is an octal non−inverting buffer/line driver/line

receiver designed to be used with 3−state memory address drivers,

clock drivers, and other bus−oriented systems. This device features

inputs and outputs on opposite sides of the package and two ANDed

active−low output enables.
