ELECTRICAL CHARACTERISTICS

Absolute Maximum Ratings()

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 and MCLR) ................................................... -0.3V to (VDD + 0.3V)

Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +7.5V

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

Total power dissipation (Note 1) ...............................................................................................................................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/RE3 pin, inducing currents greater than 80 mA, may cause

latch-up. Thus, a series resistor of 50-100

Ω should be used when applying a “low” level to the MCLR/VPP/

RE3 pin, rather than pulling this pin directly to VSS.

Note:

Other than some basic data, this section documents only the PIC18F2423/2523/4423/4523 devices’ specifi-

cations that differ from those of the PIC18F2420/2520/4420/4520 devices. For detailed information on the

electrical specifications shared by the PIC18F2423/2523/4423/4523 and PIC18F2420/2520/4420/4520

devices, see the “PIC18F2420/2520/4420/4520 Data Sheet” (DS39631).

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.
