ELECTRICAL CHARACTERISTICS FOR PIC14000
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) ...................................................... -0.5V to VDD +0.6V
Voltage on VDD with respect to VSS .............................................................................................................. 0 to +6.0 V
Voltage on MCLR with respect to VSS (Note 2) ...............................................................................................0 to +14 V
Total power Dissipation (Note 1) ..............................................................................................................................1.0 W
Maximum Current out of VSS pin ...........................................................................................................................300mA
Maximum Current into VDD pin ..............................................................................................................................250mA
Input clamp current, IIK (VI <0 or VI> VDD)
.........................................................................................................................±20mA
Output clamp current, IOK (VO <0 or VO>VDD)
...................................................................................................................±20mA
Maximum Output Current sunk by any I/O pin .........................................................................................................25mA
Maximum Output Current sourced by any I/O pin....................................................................................................25mA
Maximum Current sunk by PORTA, PORTC, and PORTD(combined) ..................................................................200mA
Maximum Current sourced by PORTA, PORTC, and PORTE (combined) ............................................................200mA
Maximum Current sunk by PORTC and PORTD (combined) ................................................................................200mA
Maximum Current sourced by PORTC and PORTD (combined) ...........................................................................200mA
Note 1: Power dissipation is calculated as follows: 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 80mA, may cause latch-up. Thus,
a series resistor of 50-100
should be used when applying a “low” level to the MCLR pin rather than pulling
this pin directly to VSS.
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 specication is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
