TECHNICAL DATA
KK74ACT244
Octal 3-State Noninverting
Buffer/Line Driver/Line Receiver
High-Speed Silicon-Gate CMOS
The KK74ACT244 is identical in pinout to the LS/ALS244,
HC/HCT244. The KK74ACT244 may be used as a level converter for
interfacing TTL or NMOS outputs to High Speed CMOS inputs.
This octal noninverting 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 noninverting outputs and two
active-low output enables.
