Input/output circuit

A method comprising:

• generating a signal at an output node of a circuit, the signal ranging between a first voltage level carried on a first power node and a second voltage level;
• and
• responsive to the signal, electrically coupling a node between the output node and the first power node to a second power node carrying a third voltage level,
• wherein,
• a difference between the first voltage level and the second voltage level has a first magnitude,
• a difference between the first voltage level and the third voltage level has a second magnitude, and
• the first magnitude is a multiple of the second magnitude having a value greater than one.
