ABSTRACT:
An ESD protection system that makes use of several different types of over-voltage protection devices provides ESD conduction paths between different power lines. For example, the system may employ shunt diodes between the ground lines of the different power supplies and between I/O pads and power supply lines; SCR protection between I/O pads and ground; and thick field device protection between different power supply V.sub.DD lines. In this way, a conduction path for an ESD event between two input, output power and ground pads may be implemented using the device whose switching characteristics are best suited to that application.
