ABSTRACT:
A method and apparatus for preventing latch-up caused by spurious signals reaching the input and output ports of an IC. The apparatus consists of a current regulating diode that limits the current entering the IC to a level below the latch-up holding level preventing the IC from being latched up. The method and apparatus further allows the recovery of an IC that has been latched-up through external transient ionizing radiation by limiting the current through the IC below the latch-up holding current level.
