Abstract
Disclosed is an input/output (IO) device for transmitting an input data bit signal. In one embodiment, the IO device includes an IO device input node for receiving the input data bit signal and an IO device output node. The IO device also includes a driver coupled between the IO device input node and the IO device output node. The driver includes at least one FET that defines a gate oxide voltage limit. The driver receives a supply voltage and the input data bit signal. The driver charges and discharges the IO device output node to the supply voltage and ground, respectively, in response to driver receiving the supply voltage and the input data bit signal. The supply voltage is greater than the gate oxide voltage limit.
