TECHNICAL DATA
IN74ACT125
Quad 3-State Noninverting Buffers
High-Speed Silicon-Gate CMOS
The IN74ACT125 is identical in pinout to the LS/ALS125, HC/HCT125.
The IN74ACT125 may be used as a level converter for interfacing TTL or
NMOS outputs to High Speed CMOS inputs.
The IN74ACT125 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.
