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.
Features
• Output Drive Capability: 15 LSTTL Loads • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.
