    How many Ohms is the resister between Pin with GND when pin is set as open drain low and pin output is low?

              I want to use I/O port as a switch to control outside resister network, I find the resister between pin with GND is not 0 ohm when the I/O pin is set a open drain low and the Pin output is low.   
      if I want to get a low resister near zero Ohm between pin with GND, How do I want to do?   
         
      Best regards,
