74HC244
Octal 3−State Noninverting
Buffer/Line Driver/
Line Receiver
High−Performance Silicon−Gate CMOS
The 74HC244 is identical in pinout to the LS244. The device inputs
are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL 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.
The HC244 is similar in function to the HC240A.
