A microchip includes at least one I/O area surrounding at least one core circuit area. The I/O area further includes a first I/O cell having at least one first post-driver device connected to a first I/O pad; a second I/O cell having at least one second post-driver device connected to a second I/O pad; and an electrostatic discharge (ESD) cluster shared by the first I/O cell and the second I/O cell for protecting the same against ESD current during an ESD event, thereby reducing a total width of the first I/O cell and the second I/O cell.
