1. An integrated circuit comprising a first impedance termination circuit, the first impedance termination circuit comprising:

  • a first termination resistor coupled to a first input/output pin on the integrated circuit;

    a common mode driver; and

    a first transistor coupled between the first termination resistor and the common mode driver, the first transistor blocking current flow through the first termination resistor when the first transistor is OFF;

    wherein a body of the first transistor is coupled to a first supply voltage.
