MAX6816 - CMOS Switch Debouncers

General Description

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.

Key Features

  • Switch Debouncer Integration Simplifies System Interface to Mechanical Switches.
  • Single-Supply Operation from +2.7V to +5.5V.
  • No External Components Required.
  • Single (MAX6816), Dual (MAX6817), and Octal (MAX6818) Versions Available.
  • 6μA Supply Current.
  • Built-In Protection Circuitry Improves System Reliability.
  • Inputs Can Exceed Power Supplies up to ±25V.
  • ESD Protection for Input Pins -- ±15kV.
  • Human Body Mode.

MAX6816/MAX6817/ MAX6818 ±15kV ESD-Protected, Single/Dual/Octal, CMOS Switch Debouncers General Description 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.
