PIC microcontroller input/output port's input impedance typical value [Ohms]?

I need a typical value for a PIC microcontroller input/output port's input impedance value in Ohms.

Please put your reference and PIC's model number.

Update:

If a feed this input port with a TTL signal (5[V]).. I need to know how much is going to be their input impedance?

    Digital inputs and outputs do not have a resistance value.

    Inputs have a low level input voltage when sourcing a specified current, and a high level voltage when sinking a specified current. Outputs have similar specs.
