Abstract
An I/O scheme for an integrated circuit includes a group layout cell. The group layout cell includes a plurality of signal I/O pads. A driver circuit is coupled to each signal I/O pad. The group layout cell also includes two I/O driver-circuit power-supply pads. ESD protection circuitry is coupled to the plurality of driver circuits. The signal I/O pads and the I/O driver-circuit power-supply pads are arranged in rows. The rows may be regular or staggered.
