CMOS
The IN74AC244 is identical in pinout to the LS/ALS244, HC/HCT244. The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with LS/ALS 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; 0.1 µA @ 25°C High Noise Immunity Characteristic of
CMOS Devices Outputs Source/Sink 24 mA
