Abstract: An integrated circuit device includes a package and at least two leads exposed external to the package to permit electrical connections to the package. A first die situated in the package has a first substrate and at least a first terminal electrically coupled to a first one of the leads. A second die situated in the package has a second substrate and at least a second terminal electrically coupled to a second one of the lead. An adhesive material holding the first and second die in place forms a voltage-triggered conduction path between the first and second die electrically that isolates the second die from the first die under a first condition and provides an ESD current path between the first one of the leads and the second one of the leads under a second condition.
