PROBLEM TO BE SOLVED: To provide a tolerant input/output circuit capable of reducing power consumption and of making operating frequency high. SOLUTION: In an input mode, a gate signal generation unit for generating a gate signal for inactivating a pull-up side output transistor P24 generates the gate signal for inactivating the pull-up side output transistor P24 in accordance with an enable signal En and an input signal Di input to an input/output terminal Tio.
