FAQ

How should unused inputs be handled?

Unused inputs must be terminated to either VCC or ground. They can be connected directly or via a pull-up/pull-down resistor, typically 10kΩ, to ensure valid logic states.

What are the absolute maximum input voltage ratings?

The input voltage range extends from -0.5 V to VCC + 0.5 V. Exceeding these limits may cause permanent damage unless clamp current ratings are observed.
