FAQ

What is the maximum input voltage tolerance?

The inputs tolerate voltages up to 6.5 V, allowing safe interfacing with 5.0 V systems even when the device is powered at lower voltages.

How does the device handle unused outputs?

Unused outputs must be left open. Unused inputs should always be tied to an appropriate logic voltage level, either GND or VCC.
