74HC125
QUADRUPLE 3-STATE BUFFERS OE LOW
Description
The 74HC125 provides provides four independent buffer gates with
3-state outputs. Each buffer has a separate enable pin that if driven
with a high logic level places the corresponding output in the high
impedance state. The device is designed for operation with a power
supply range of 2.0V to 6.0V.
Pin Assignments
