Abstract
An input/output circuit for increasing immunity to voltage spikes from voltage supplies is provided. The circuit includes a first pair of transistors each having their drains connected to an output terminal and their sources connected to voltage supplies. A mechanism is connected to electrically separated voltage supplies to alternately turn on one of the first pair of transistors responsive to an input signal. A transistor is utilized to provide feedback to limit the rise in a ground voltage supply as occurs during ground bounce.
