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.
