Контрольные цепи MAX6818EAP+.

Специализированный интерфейс , КМОП

The MAX6818EAP+ is an octal CMOS Switch Debouncer for membrane keypads and µP switch interfacing. The switch debouncers that provide clean interfacing of mechanical switches to digital systems. They accept one or more bouncing inputs from a mechanical switch and produce 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 +2.7 to +5.5V. Under-voltage-lockout circuitry ensures the output is in the correct state upon power-up. The MAX6818 octal switch debouncer is designed for data-bus interfacing. The MAX6818 monitors switches and provides a switch change-of-state output (CH), simplifying microprocessor (µP) polling and interrupts.
