17.0 PIC17C42 ELECTRICAL CHARACTERISTICS
Absolute Maximum Ratings â
Ambient temperature under bias..................................................................................................................-55 to +125ËC
Storage temperature ............................................................................................................................... -65ËC to +150ËC
Voltage on VDD with respect to VSS ................................................................................................................ 0 to +7.5V
Voltage on MCLR with respect to VSS (Note 2) ..........................................................................................-0.6V to +14V
Voltage on RA2 and RA3 with respect to VSS..............................................................................................-0.6V to +12V
Voltage on all other pins with respect to VSS ..................................................................................... -0.6V to VDD + 0.6V
Total power dissipation (Note 1).................................................................................................................................1.0W
Maximum current out of VSS pin(s) - Total .............................................................................................................250 mA
Maximum current into VDD pin(s) - Total ................................................................................................................200 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 (except RA2 and RA3)......................................................................35 mA
Maximum output current sunk by RA2 or RA3 pins .................................................................................................60 mA
Maximum output current sourced by any I/O pin .....................................................................................................20 mA
Maximum current sunk by PORTA and PORTB (combined)..................................................................................150 mA
Maximum current sourced by PORTA and PORTB (combined).............................................................................100 mA
Maximum current sunk by PORTC, PORTD and PORTE (combined)...................................................................150 mA
Maximum current sourced by PORTC, PORTD and PORTE (combined)..............................................................100 mA
Note 1: Power dissipation is calculated as follows: Pdis = VDD x {IDD - â IOH} + â {(VDD-VOH) x IOH} + â(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 "low" level to the MCLR pin rather than
pulling this pin directly to VSS.
â 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 speciï¬cation is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
