TECHNICAL DATA
Octal 3-State Noninverting
Buffer/Line Driver/Line Receiver
High-Performance Silicon-Gate CMOS
IN74HC244A
The IN74HC244A is identical in pinout to the LS/ALS244. The
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL 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
• High Noise Immunity Characteristic of CMOS Devices
