Abstract
An electrostatic discharge protection circuit may include ovonic threshold switches that have a holding voltage greater than an input voltage normally received from a pad. As a result, the ovonic threshold switches provide a low resistance state to shunt current from the pad when an electrostatic discharge protection event occurs and, otherwise, present an off device during normal circuit operations.
