ELECTRICAL CHARACTERISTICS
15.1
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 VSS (except VDD and MCLR).................................................... -0.6V to (VDD + 0.6V)
Voltage on VDD with respect to VSS ................................................................................................................ 0 to +7.5V
Voltage on MCLR with respect to VSS (Note 2)..................................................................................................0 to +14V
Total power Dissipation (Note 1) ..........................................................................................................................800 mW
Maximum Current out of VSS pin...........................................................................................................................150 mA
Maximum Current into VDD pin................................................................................................................................50 mA
Maximum Current into an input pin
..................................................................................................................................±500 A
Maximum Output Current sunk by any I/O pin ........................................................................................................25 mA
Maximum Output Current sourced by any I/O pin ...................................................................................................20 mA
Maximum Output Current sourced by a single I/O port (PortA or B) .......................................................................40 mA
Maximum Output Current sunk by a single I/O port (PortA or B) ............................................................................50 mA
Note 1: Total power dissipation should not exceed 800 mW for the package. Power dissipation is calculated as fol-
lows: Pdis = VDD x {IDD -
∑ IOH} + ∑ {(VDD-VOH) x IOH} + ∑(VOL x IOL)
Note 2: Voltage spikes below VSS at the MCLR pin, inducing currents greater than 80 mA, may cause latch-up. Thus,
a series resistor of 50-100
should be used when applying a “l(fā)ow” level to the MCLR pin rather than pulling
this pin directly to VSS.
TABLE 15-1:
CROSS REFERENCE OF DEVICE SPECS FOR OSCILLATOR CONFIGURATIONS
AND FREQUENCIES OF OPERATION (COMMERCIAL DEVICES)
* 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.

but not for MIN/MAX specifications. It is
recommended that the user select the
device
type
that
guarantees
the
specifications required.
