4.1.3
The MCP65R41/6 comparator family uses CMOS tran-
sistors at the input. They are designed to prevent
phase inversion when the input pins exceed the supply
voltages.
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 a 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
A greater flexibility in selecting the hysteresis (or the
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.
