Octal 3−State Noninverting Buffer/Line Driver/Line Receiver
High–Performance Silicon–Gate CMOS
The MC74HC244A 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 HC244A is similar in function to the HC240A.
