Integrated circuit device, has protection cell with power supply voltage and ground voltage protection units and power clamp unit, where units are placed adjacent to each other so that they can be connected in straight line

摘要

The device has an I/O electrostatic discharge (ESD) protection cell (130) with power supply voltage (VDD) and ground voltage (V) ESD protection units and a power clamp unit. The VDD unit is coupled between a pad and a VDD line (160). The clamp unit is connected between the VDD line and a V line. The units are placed adjacent to each other so that they can be connected in straight line/arranged to partially overlap.
