TECHNICAL DATA
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.
