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.
