Quad 3-State Noninverting Buffers
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LS/ALSTTL outputs.
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
• High Noise Immunity Characteristic of CMOS Devices
The IN74HC125A is identical in pinout to the LS/ALS125. The device
The IN74HC125A noninverting buffers are designed to be used with 3-
