Abstract: The present disclosure relates to electrostatic protection terminals. One example terminal includes a target interface, a protected circuit, a protection unit, a switch unit, and a switch control unit. The protected circuit is configured to suppress an electrostatic discharge (ESD) current or an electrical overstress (EOS) current. A first end of the protection unit is electrically connected to a first pin of the target interface. A second end of the protection unit is electrically connected to a second pin of the protected circuit. The first pin is any pin of the target interface. The second pin is a pin that is in the protected circuit and that needs to be electrically connected to the first pin. The switch unit is connected to the protection unit in parallel. The switch control unit is configured to control the switch unit to be open or closed.
