IN74ACT244
OCTAL 3-STATE NONINVERTING
BUFFER/LINE DRIVER/LINE RECEIVER
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
