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
