ABSTRACT:
A discharge guard circuit for use in combination with an integrated circuit that prevents the integrated circuit logic from damage or upset caused by system generated electromagnetic pulses at the integrated circuit outputs. The integrated circuit core logic is isolated from the output drivers and the discharge guard circuit, and the integrated circuit is configured to route system generated electromagnetic pulse current through the discharge guard circuit and out of the integrated circuit.
