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.
