74HC244

Octal 3−State Noninverting

Buffer/Line Driver/

Line Receiver

High−Performance Silicon−Gate CMOS

http://onsemi.com

The 74HC244 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.

MARKING

DIAGRAM

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.
