<p>A cascoded input-output device is provided configured to receive at an input node a lower voltage input signal and to generate at an output node a higher voltage output signal. The input-output device is split into two voltage domains to enable output signals in a larger range to be generated, while the components of the input-output device individually operate in a smaller range. By applying a selected bias voltage to a protected node of the cascoded input-output device, first changing that selected bias voltage in response to a transition of the input signal and then switching that selected bias voltage back when the output signal reaches a predetermined level, that node is protected, either avoiding stress-inducing voltage swings or providing a switching speed increasing charge boost.</p> |
