IN74ACT244

1

High-Speed Silicon-Gate CMOS

The IN74ACT244 is identical in pinout to the LS/ALS244,

HC/HCT244. The IN74ACT244 may be used as a level converter

for interfacing TTL or NMOS outputs to High Speed CMOS

inputs.

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.

• 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; 0.1 µA @ 25°C

• Outputs Source/Sink 24 mA
