TECHNICAL DATA
KK74HCT244A
Octal 3-State Noninverting
Buffer/Line Driver/Line Receiver
High-Performance Silicon-Gate CMOS
The
KK74HCT244A
is identical in pinout to the LS/ALS244. The
device may be used as a level converter for interfacing TTL or NMOS
outputs to High-Speed CMOS inputs.
The
KK74HCT244A
is an octal noninverting buffer/line driver/line
receiver designed to be used with 3-state memory address drivers, clock
drivers, and other bus-oriented systems. The device has non-inverted
outputs and two active-low output enables.
