Quad 3-State Noninverting Buffers
High-Speed Silicon-Gate CMOS
KK74AC125
The KK74AC125 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 KK74AC125 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.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 µA; 0.1 µA @ 25°C
• High Noise Immunity Characteristic of CMOS Devices
• Outputs Source/Sink 24 mA
