Abstract
An integrated circuit includes a bidirectional ESD device which has a plurality of parallel switch legs. Each switch leg includes a first current switch and a second current switch in a back-to-back configuration. A first current supply node of each first current switch is coupled to a first terminal of the ESD device. A second current supply node of each second current switch is coupled to a second terminal of the ESD device. A first current collection node of each first current switch is coupled to a second current collection node of the corresponding second current switch. The first current collection nodes in each first current switch is not coupled to any other first current collection node, and similarly, the second current collection node in each instance second current switch is not coupled to any other second current collection node.
