MC74HC540A
Octal 3-State Inverting
Buffer/Line Driver/Line
Receiver
High−Performance Silicon−Gate CMOS
The MC74HC540A is identical in pinout to the LS540. The device
inputs are compatible with Standard CMOS outputs. External pull−up
resistors make them compatible with LSTTL outputs.
The HC540A is an octal 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.
The HC540A is similar in function to the HC541A, which has
noninverting outputs.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
