Ambient temperature under bias.....................................................-40°C to +125°C
Storage temperature ..................................................................... -65°C to +150°C
Voltage on any pin with respect to V_SS (except V_DD and MCLR)..-0.3V to (V_DD + 0.3V)

Voltage onMCLR with respect to V_SS(Note 2)...........................................-0.3 to +14V
Total power dissipation (Note 1) ..............................................................................1W
Maximum current out of V_SS pin ..........................................................................200 mA
Maximum current into V_DD pin .............................................................................200 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

Note 1: Power dissipation is calculated as follows: Pdis = V_DD x {I_DD I_OH} + {(V_DD V_OH) x I_OH} + (V_OL x I_OL)
2: Voltage spikes at theMCLR pin may cause latch-up. A series resistor of greater than 1 k should be used
to pullMCLR to V_DD, rather than tying the pin directly to V_DD.

† 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.
