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.
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.
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.
Additionally, the MAX6818 has three-state outputs con-
trolled by an enable (EN) pin, and is pin-compatible
with the LS573 octal latch (except for the CH pin),
allowing easy interfacing to a digital data bus.
