4.1.3
The MCP6561/1R/1U/2/4 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 push-pull output is designed to be compatible with
CMOS and TTL logic, while the output transistors are
configured to give rail-to-rail output performance. They
are driven with circuitry that minimizes any switching
current (shoot-through current from supply-to-supply)
when the output is transitioned from high-to-low, or
from low-to-high (see
more information).
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.
