... Octal 3-State Noninverting Buffer/Line Driver/Line Receiver High-Performance Silicon-Gate CMOS The IN74HC244A is identical in pinout to the LS/ALS244. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL 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 ...
