Io driver circuit with output stage configurable as a thevenin terminator

A circuit arrangement, comprising:

• an input/output node;
• a receiver circuit comprising an input configured to receive an input signal from the input/output node;
• a driver circuit comprising an input and an output, the output configured to communicate an output signal to the input/output node responsive to an input signal received at the input, the driver circuit comprising an output stage coupled between the input and the output of the driver circuit, the output stage including first, second, third and fourth branches coupled in parallel to one another, each branch including a pull-up device and a pull-down device coupled to the output;
• and
• an output stage control circuit coupled to the output stage to selectively configure the output stage to operate as a thevenin termination for the input/output node when the receiver circuit is receiving the input signal, wherein the output stage control circuit configures the output stage to operate as a thevenin termination by concurrently activating the pull-up devices in the first and second branches and the pull-down devices in the third and fourth branches, while deactivating the pull-up devices in the third and fourth branches and the pull-down devices in the first and second branches.
