Description
Manufacturer
Integral Corp.
Datasheet
Octal 3-State Noninverting
Buffer/Line Driver/Line Receiver
High-Speed Silicon-Gate CMOS
HC/HCT244. The IN74ACT244 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
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
The IN74ACT244 is identical in pinout to the LS/ALS244,
This octal noninverting buffer/line driver/line receiver is
