Ambient temperature under bias.....................................................................................................-40°C to +125°C
Storage temperature ..................................................................................................................... -65°C to +150°C
Voltage on any pin with respect to VSS (except VDD, MCLR and RA4) ......................................... -0.3V to (VDD + 0.3V)
Voltage on VDD with respect to VSS ...................................................................................................... -0.3V to +5.5V
Voltage onMCLR with respect to VSS (Note 2) ...................................................................................... 0V to +13.25V
Voltage on RA4 with respect to VSS............................................................................................................ 0V to +8.5V
Total power dissipation (Note1) ............................................................................................................................1.0W
Maximum current out of VSS pin .........................................................................................................................300 mA
Maximum current into VDD pin ............................................................................................................................250 mA
Input clamp current, IIK (VI < 0 or VI > vDD)..................................................................................................... ±20 mA
Output clamp current, IOK (VO < 0 or VO > VDD) ............................................................................................... ±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 50-100 should be used when applying a "low" level to the MCLR/VPP pin, rather than pulling this pin directly to VSS.
