Maximum current sourced by PORTC and PORTD (combined) (Note 3) ............................................................200 mA
Note 1: Power dissipation is calculated as follows: Pdis = V
2: Voltage spikes below V
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
3: PORTD and PORTE are not implemented on PIC16F873A/876A 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.
