KK74HCT125A

Quad 3-State Noninverting Buffers

High-Performance Silicon-Gate CMOS

ORDERING INFORMATION

KK74HCT125AN Plastic

KK74HCT125AD SOIC

The KK74HCT125A is identical in pinout to the LS/ALS125. The

KK74HCT125A may be used as a level converter for interfacing TTL or

NMOS outputs to High Speed CMOS inputs.

The KK74HCT125A 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
