More Information
Summary:A semiconductor device includes a first driver configured to pull up a voltage level of a pad to a first power voltage in response to a driving signal, a second driver configured to pull down the voltage level of the pad to a second power voltage in response to the driving signal, a switch protection resistor configured to change an electrical resistance between the pad and the second driver in response to a switch control signal, and an ESD detector configured to detect a voltage level of the first or second power voltage and generate the switch control signal.
