ABSTRACT:
Input transistors have sources which are connected to a first input reference node and gates to which a pair of input signals are input. Input-side voltage relaxing transistors have sources connected to drains of the pair of input transistors and gates connected to a second input reference node. Output-side voltage relaxing transistors have sources connected to output nodes, gates connected to a first output reference node, and drains connected to drains of the input-side voltage relaxing transistors. First and second inverter circuits are in correspondence with the output nodes, and are connected between second and third output reference nodes. Each of the first and second inverter circuits also supplies a voltage at one of the second and third output reference nodes to its corresponding one of the output nodes, depending on a voltage at its non-corresponding one of the output nodes.
