MC74HC244AN 数据手册

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.
