Patent ID: 8854078

Claim:
An integrated circuit comprising receiver circuitry operable to: enable a conductive path between an integrated circuit input/output pad and a first supply voltage when an input signal is in a first logic state and an enabling signal is in a second logic state; disable the conductive path between the input/output pad and the first supply voltage when both the input signal and the enabling signal are in the second logic state; disable the conductive path between the input/output pad and the first supply voltage when a programmable bit and the enabling signal are in the first logic state; and enable the conductive path between the input/output pad and the first supply voltage when the programmable bit is in the second logic state and the enabling signal is in the first logic state, the enabling of the conductive path between the input/output pad and the first supply voltage being independent of an output signal of the input/output pad, wherein the enabling of a conductive path is accomplished using a transistor, a gate voltage of the transistor being independent of the output signal.
