† Notice: Stresses above those listed under “Absolute 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 sections of this specification is not intended. Exposure to maximum rating conditions for extended
periods may affect device reliability.
Note 1: T
A
= +25°C.
2: Derate at the rate of 20 mW/°C above T
A
= +25°C.
3: Microchip CMOS devices have input-static protection, but are susceptible to damage when exposed to
extremely high static electrical charges.
