Buffers, Drivers, Receivers, Transceivers FAQ

How does the output behave when the device is powered off?

The integrated Ioff circuit disables the outputs and prevents current from flowing backward through the pins, protecting upstream components during partial power-down scenarios.

What is the function of the OE (Output Enable) input?

The OE input controls the three-state output. When OE is low, the output enters a high-impedance state; when OE is high, the input data is transmitted to the output.
