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