ABSTRACT:
A circuit for isolating an interconnect line from unwanted input signal voltage levels is described. One implementation of the circuit includes a transmission gate coupled in series between an input signal and an interconnect line having its gate coupled to the output of an inverter and the input of the inverter coupled to the input signal. The inverter senses the input signal and when it sense voltages that are either too high or low, the isolation circuit decouples the input signal from the interconnect line such that the input signal can transition independently with respect to the voltage levels on the interconnect line.
