Product Overview
MC74HC540A: Octal 3-State Inverting Buffer/Line Driver/Line Receiver
For complete documentation, see the data sheet
Product Description
High-Performance Silicon-Gate CMOS
The MC74HC540A is identical in pinout to the LS540. The device inputs are compatible with Standard CMOS outputs. External
pullup 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 non-inverting outputs.
