PROBLEM TO BE SOLVED: To provide a tri-state buffer circuit with a small area and also with small delay and an integrated circuit having the tri-state buffer circuit. SOLUTION: A tri-state buffer is constituted of a small number of components by coupling a prestage circuit of the tri-state buffer with the tri-state buffer. The tri-state buffer has the small area, in addition to that, has an ability for compensating delay difference between rise and fall of a signal and delay of the entire circuit is reduced by using the ability. A circuit in the case of using a multiplexer is specifically constituted as the most useful prestage circuit. COPYRIGHT: (C)2004,JPO
