Product Overview MC74HC244A: Octal 3-State Non-Inverting Buffer/Line Driver/Line Receiver For complete documentation, see the data sheet Product Description 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 and HC241A.
