IN74HCT244A

Octal 3-State Noninverting

Buffer/Line Driver/Line Receiver

High-Performance Silicon-Gate CMOS

ORDERING INFORMATION

IN74HCT244AN

Plastic

IN74HCT244ADW SOIC

The IN74HCT244A is identical in pinout to the LS/ALS244. The de-

vice may be used as a level converter for interfacing TTL or NMOS out-

puts to High-Speed CMOS inputs.

The IN74HCT244A is an octal noninverting buffer/line driver/line re-

ceiver designed to be used with 3-state memory address drivers, clock driv-

ers, and other bus-oriented systems. The device has non-inverted outputs

and two active-low output enables.

• TTL/NMOS-Compatible Input Levels

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 4.5 to 5.5 V

• Low Input Current: 1.0 µA
