10.0 ELECTRICAL CHARACTERISTICS - PIC16HV540
Absolute Maximum Ratings
†
Ambient temperature under bias.............................................................................................................. –20°C to +85°C
Storage temperature ............................................................................................................................. –65°C to +150°C
Voltage on V
DD with respect to VSS ...................................................................................................................0 to +16V
Voltage on MCLR
with respect to VSS................................................................................................................0 to +14V
Voltage on all other pins with respect to V
SS ................................................................................. –0.6V to (VDD + 0.6V)
Total power dissipation
(1)
.....................................................................................................................................800 mW
Max. current out of V
SS pin ...................................................................................................................................150 mA
Max. current into V
DD pin ......................................................................................................................................100 mA
Max. current into an input pin (T0CKI only) .....................................................................................................................±500 µA
Input clamp current, I
IK (VI < 0 or VI > VDD) ...................................................................................................................±20 mA
Output clamp current, I
OK (VO < 0 or VO > VDD) ..............................................................................................................±20 mA
Max. output current sunk by any I/O pin .................................................................................................................25 mA
Max. output current sourced by any I/O pin ............................................................................................................10 mA
Max. output current sourced by a single I/O port A or B .........................................................................................40 mA
Max. output current sourced by a single I/O port A or B ........................................................................................50 mA
Note 1: Power dissipation is calculated as follows: Pdis = V
DD x {IDD - ∑ IOH} + ∑ {(VDD-VOH) x IOH} + ∑(VOL x IOL)
2: Voltage spikes below V
SS at the MCLR pin, inducing currents greater than 80mA, may cause latch-up. Thus,
a series resistor of 50-100Ω should be used when applying a “low” level to the MCLR
pin rather than pulling
this pin directly to V
SS.

NOTICE: Stresses above those listed under "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 indi-
cated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
