TECHNICAL DATA
Octal 3-State Inverting Buffer/Line
Driver/Line Receiver
High-Performance Silicon-Gate CMOS
KK74HC240A
The KK74HC240A 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 bus-
oriented 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
