SOT switch debouncer features ±15kV ESD protection and ±25V fault tolerance

The MAX6816 is a single switch debouncer that provides clean interfacing of mechanical switches to digital systems. It accepts one or more bouncing inputs from a mechanical switch and produces a clean digital output after a short, preset qualification delay.

Both the switch opening bounce and the switch closing bounce are removed. Robust switch inputs handle ±25V levels and are ±15kV ESD-protected for use in harsh industrial environments. They feature single-supply operation from +2.7V to +5.5V. Undervoltage lockout circuitry ensures the output is in the correct state upon power-up.

The single MAX6816 and dual MAX6817 are offered in SOT packages and require no external components. Their low supply current makes them ideal for use in portable equipment.
