ABSTRACT:
An integrated circuit (20) includes an ESD protection circuit (50) to protect it from excessive electrostatic discharge voltages. The ESD protection circuit (50) includes a diode (51) in series with a silicon controlled rectifier (SCR) (60) connected between an input signal line (42) and a power supply voltage terminal. Unlike conventional protection circuits, the ESD protection circuit (50) allows the voltage on the input signal line (42) to extend well beyond positive and negative power supply potentials, and only becomes conductive to discharge voltages which are outside of this extended range.
