TECHNICAL DATA
Quad 3-State Noninverting Buffers
High-Speed Silicon-Gate CMOS
IN74AC125
The IN74AC125 is identical in pinout to the LS/ALS125, HC/HCT125. The device inputs are compatible with
standard CMOS outputs; with pullup resistors, they are compatible with
LS/ALS outputs.
The IN74AC125 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.
