The MCP6566/6R/6U/7/9 comparator family uses
CMOS transistors at the input. They are designed to
prevent phase inversion when the input pins exceed
the supply voltages.
exceeding both supplies with no resulting phase
inversion.
4.2
The open-drain output is designed to make
level-shifting and wired-OR logic easy to implement.
The output stage minimizes switching current
(shoot-through current from supply-to-supply) when
the output changes state. See
4.3
Greater flexibility in selecting hysteresis (or input trip
points) is achieved by using external resistors.
Hysteresis reduces output chattering when one input is
slowly moving past the other. It also helps in systems
where it is best not to cycle between high and low
states too frequently (e.g., air conditioner thermostatic
control). Output chatter also increases the dynamic
supply current.
