MC74HC541A

Octal 3-State Noninverting

Buffer/Line Driver/Line

Receiver

High−Performance Silicon−Gate CMOS

The MC74HC541A is identical in pinout to the LS541. The device

inputs are compatible with Standard CMOS outputs. External pull−up

resistors make them compatible with LSTTL outputs.

The HC541A is an octal noninverting 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.

The HC541A is similar in function to the HC540A, which has

inverting outputs.
