Abstract
An integrated circuit supports multiple communication modes using different input/output (IO) voltages. The IC includes a low-voltage communication circuit operating at a low IO voltage in a low-voltage mode, and a high-voltage communication circuit operating at a high IO voltage in a high-voltage mode. The low-voltage communication circuit includes low-voltage transistors in a critical path that exhibits sensitivity to a destructive voltage less than the high IO voltage. The low-voltage communication circuit is therefore provided with protection circuitry to protect the low-voltage transistors from the high 10 voltage.
