In the datasheets for PIC mcus, they have a max spec labeled "Capacitive Loading Specs On Output Pins." See page 254 of the 16f886 data sheet. I just recently got a handle on the whole \(\large I=C\) \(\frac{dv}{dt}\) thing. So now I'm wondering what that spec means exactly. My goal is to drive a logic level mosfet directly from the PIC with a series resistor between the PIC output and the mosfet gate to keep the current draw below 25mA. I will also have a pulldown resistor on the gate to keep the gate from floating when the circuit is unpowered. So I know I'm safe with the setup. I am just wondering what that rating means. If I were to drive a 50pF load with no series resistor and the rise time of the output pin is 2nS (p259 of the spec sheet) the current required is much higher than 25mA. So what gives?
