Abstract
A discharge unit is connected to a power pad, a ground pad, and an I/O pad, and can discharge an electrostatic charge when an electrostatic pulse appears on any of the power pad, the ground pad, and the I/O pad. The discharge unit includes a first discharge unit and a second discharge unit, the first discharge unit is connected to the second discharge unit, the power pad, and the I/O pad, and the second discharge unit is connected to the ground pad and the I/O pad. The first discharge unit and/or the second discharge unit can discharge electrostatic charges on different pads, respectively.
