Absolute Maximum Ratings (†)

Ambient temperature under bias.............................................................................-55°C to +125°C

Storage temperature ............................................................................................. -65°C to +150°C Voltage on any pin with respect to V_SS (except V_DD, MCLR and RA4) ........... -0.3V to (V_DD + 0.3V)

Voltage on V_DD with respect to V_SS ........................................................................... -0.3V to +7.5V

Voltage on MCLR with respect to V_SS (Note 2) .......................................................... 0V to +13.25V

Voltage on RA4 with respect to V_SS ............................................................................... 0V to +8.5V

Total power dissipation (Note 1) ...............................................................................................1.0W

 

Maximum current out of V_SS pin ............................................................................................300 mA

Maximum current into V_DD pin ...............................................................................................250 mA

Input clamp current, I_IK (V_I < 0 or V_I > V_DD)........................................................................... ±20 mA

Output clamp current, I_OK (V_O < 0 or V_O > V_DD).................................................................... ±20 mA

Maximum output current sunk by any I/O pin.............................................................................25 mA

Maximum output current sourced by any I/O pin .......................................................................25 mA

Maximum current sunk by all ports ..........................................................................................200 mA

Maximum current sourced by all ports .....................................................................................200 mA

Note

1: Power dissipation is calculated as follows:

    Pdis = VDD x {IDD - ∑ IOH} + ∑ {(VDD-VOH) x IOH} + ∑(VOl x IOL)

2: Voltage spikes below VSS at the MCLR/VPP pin, inducing currents greater than 80 mA, may cause latch-up. Thus, a series resistor of 50-100Ω should be used when applying a “low” level to the MCLR/VPP pin, rather than pulling this pin directly to VSS.

 

† 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 operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.
