Patent abstract
The present invention discloses an electrostatic discharge device for ensuring a pin capacitance using a metal option. The electrostatic discharge device includes an electrostatic discharging unit formed between a power source voltage line and a ground voltage line to discharge static electricity input from a pad. A MOS capacitor of the electrostatic discharge device has a gate terminal connected to the pad via a metal option. A protection unit is formed between the electrostatic discharging unit and the ground voltage line to protect an internal circuit from static electricity stored in the electrostatic discharging unit.
