TECHNICAL DATA
IN74AC244
Octal 3-State Noninverting
Buffer/Line Driver/Line Receiver
High-Speed Silicon-Gate CMOS
The IN74AC244 is identical in pinout to the LS/ALS244,
HC/HCT244. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LS/ALS
outputs.
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.
