MAX6817EUT+T

监控电路 Dual Switch Debouncer

±15kV ESD-Protected, Single/Dual/Octal,  CMOS Switch Debouncers

General Description MAX6817EUT+T

The MAX6816/MAX6817/MAX6818 are single, dual, and  octal 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 +2.7V to +5.5V.  Undervoltage-lockout circuitry ensures the output is in  the correct state upon power-up.
