Overview

SL74HC244 Octal 3-State Noninverting Buffer/Line Driver/Line Receiver High-Performance Silicon-Gate CMOS The SL74HC244 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.
The device has noninverting outputs and two active-low output enables.
