SL74HC244
Octal 3-State Noninverting
Buffer/Line Driver/Line Receiver
High-Performance Silicon-Gate CMOS
The SL74HC244 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
