IN74HCT125A

QUAD 3-STATE NONINVERTING BUFFERS

High-Performance Silicon-Gate CMOS

The IN74HCT125A is identical in pinout to the LS/ALS125.

The IN74HCT125A may be used as a level converter for

interfacing TTL or NMOS outputs to High Speed CMOS inputs.

The IN74HCT125A 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
