TECHNICAL DATA

Quad 3-State Noninverting Buffers

High-Performance Silicon-Gate CMOS

IN74HC125A

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 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

• High Noise Immunity Characteristic of CMOS Devices
