Abstract
In some examples, a device includes a first power supply node, an input-output node, and a second power supply node positioned between the first power supply node and the input-output node. The device also includes a protection element configured to block a parasitic flow of carriers between the first power supply node and the input-output node, wherein the parasitic flow of carriers is based on a voltage level of the second power supply node.
