TECHNICAL DATA
Octal 3-State Inverting Buffer/Line
Driver/Line Receiver
High-Speed Silicon-Gate CMOS
KK74ACT240
The KK74ACT240 is identical in pinout to the LS/ALS240,
HC/HCT240. The KK74ACT240 may be used as a level converter for
interfacing TTL or NMOS outputs to High Speed CMOS inputs.
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.
⢠TTL/NMOS Compatible Input Levels
⢠Outputs Directly Interface to CMOS, NMOS, and TTL
⢠Operating Voltage Range: 4.5 to 5.5 V
⢠Low Input Current: 1.0 µA; 0.1 µA @ 25°C
⢠Outputs Source/Sink 24 mA
