Octal 3-State Inverting Buffer/Line Driver/Line Receiver
High-Performance Silicon-Gate CMOS

The SL74HC240 is identical in pinout to the LS/ALS240. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
This octal inverting buffer/line driver/line receiver is designed to be used with 3-state memory address drivers, clock drivers, and other busoriented systems. The device has inverting outputs and two active-low output enables.

 • Outputs Directly Interface to CMOS, NMOS, and TTL
 • Operating Voltage Range: 2.0 to 6.0 V
 • Low Input Current: 1.0 μA
 • High Noise Immunity Characteristic of CMOS Devices
