Abstract
Semiconductor devices and related electrostatic discharge (ESD) protection methods are provided. An exemplary semiconductor device includes an interface for a signal and a multi-triggered protection arrangement coupled between the interface and a reference node to initiate discharge of the signal between the interface and the reference node based on any one of a plurality of different characteristics of the signal. Discharge of the signal at the interface is initiated based on a first characteristic of the signal, and thereafter, the discharge of the signal at the interface is maintained based on another characteristic of the signal.
