Buffers, Drivers, Receivers, Transceivers FAQ

How does the Output Enable (OE) pin function?

When OE is low, the device passes noninverted data from inputs to outputs. When OE is high, the outputs enter a high-impedance state.

What is the recommended handling procedure for unused inputs?

Unused inputs must be held at VCC or GND to ensure proper device operation and prevent excessive power consumption.
