TECHNICAL DATA

IN74ACT125

Quad 3-State Noninverting Buffers

High-Speed Silicon-Gate CMOS

ORDERING INFORMATION

IN74ACT125N Plastic

IN74ACT125D SOIC

The IN74ACT125 is identical in pinout to the LS/ALS125, HC/HCT125.

The IN74ACT125 may be used as a level converter for interfacing TTL or

NMOS outputs to High Speed CMOS inputs.

The IN74ACT125 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.

• TTL/NMOS Compatible Input Levels

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 4.5 to 5.5 V

• Low Input Current: 1.0 µA; 0.1 µA @ 25°C

• Outputs Source/Sink 24 mA
