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.
