This quadruple bus buer gate is designed for

CC operation.

The SN74LVC125A features independent line

associated output-enable ( OE) input is high.

To ensure the high-impedance state during po

CC through a p

resistor; the minimum value of the resistor is d

Inputs can be driven from either 3.3-V or 5-V d

a mixed 3.3-V/5-V system environment.
