TECHNICAL DATA

IN74AC244

Octal 3-State Noninverting

Buffer/Line Driver/Line Receiver

High-Speed Silicon-Gate CMOS

ORDERING INFORMATION

IN74AC244N Plastic

IN74AC244DW SOIC

The

IN74AC244

is

identical

in

pinout

to

the

LS/ALS244,

HC/HCT244. The device inputs are compatible with standard CMOS

outputs; with pullup resistors, they are compatible with LS/ALS 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.

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 μA; 0.1 μA @ 25°C

• High Noise Immunity Characteristic of CMOS Devices

• Outputs Source/Sink 24 mA
