TECHNICAL DATA

Quad 3-State Noninverting Buffers

High-Speed Silicon-Gate CMOS

IN74AC125

The IN74AC125 is identical in pinout to the LS/ALS125,

HC/HCT125. The device inputs are compatible with standard CMOS

outputs; with pullup resistors, they are compatible with LS/ALS outputs.

The IN74AC125 noninverting buffers are designed to be used with 3-

state 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; 0.1 µA @ 25°C

• High Noise Immunity Characteristic of CMOS Devices

• Outputs Source/Sink 24 mA
