Abstract
Disclosed is an input/output (IO) device for transmitting a data bit signal. In one embodiment, the IO device includes an IO device input node for receiving an input data bit signal and an IO device output node. Additionally, the IO device includes a plurality of drivers coupled between the IO device input and output nodes, each having first and second n-channel FETs coupled together, first and second p-channel FETs coupled together. A drain of each driver's second n-channel FET and each driver's first p-channel FET is coupled to the IO device output node, while a gate of each driver's first n-channel FET is coupled to the IO device input node.
