†Notice: Stresses above those listed under “Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at those or any other conditions above those
indicated in the operational listings of this specification
is not implied. Exposure to maximum rating conditions
for extended periods may affect device reliability.

Note 1: The input offset voltage is the center (average) of the input-referred trip points. The input hysteresis is the
difference between the input-referred trip points.
2: Limit the output current to Absolute Maximum Rating of 30 mA.
3: Do not short the output of the MCP65R46 comparators above V
SS
+ 10V.
4: The low-power reference voltage pin is designed to drive small capacitive loads. See Section 4.5.2.
