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

BACKGROUND An electrostatic discharge (ESD) device in an integrated circuit may provide
from both positive and negative Voltage events. It may be desirable for the ESD device to be
capable of shunting a large current in an ESD event, and also be capable of providing in a
sustained ESD event without current crowding. Providing these capabilities while main
taining a desired size of the ESD device may be problematic.
