Title: Cmos output circuit
Inventor: NAKAO KENJI
IPC: H03K17/16
Filed: 1990-11-19
Abstract: PURPOSE:To drive a load at a high speed and to suppress the generation of a ringing by conducting power between the plural output terminals of output circuit only during a period of transition state after the inversion of an input signal. CONSTITUTION:When the input signal from the terminal 11 is inverted, second output circuits 2P-2N are immediately switched since the loads are not present thereon and first output circuits 1P, 1N have a load since an output terminal is connected with the output terminal 12 to be delayed. Only during the period of the transition state where potential differences are present on the respective the first and the second output circuits an electric current flows through N- channel transistor 3N or N-channel transistor 4N. Also when electric potentials are equal, the electric current stops the flow. When the voltage of the terminal 12 is high, big current driving ability is obtd. As the output voltage is lowered and approaches a ground voltage, the current driving ability becomes smaller. Thus ON resistance Ron of the output circuit is prevented from becoming too small and the generation of ringing is suppressed.
