TECHNICAL DATA
IN74HC125A
Quad 3-State Noninverting Buffers
High-Performance Silicon-Gate
CMOS
The IN74HC125A is identical in pinout to the LS/ALS125. The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The IN74HC125A noninverting buffers are designed to be used with 3state memory address drivers, clock drivers, and other bus-oriented systems. The devices have four separate output enables that are active-low. 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
