Abstract
There is disclosed a MOS transistor output circuit capable of suppressing ringing and other noises and of operating at high speed under low power supply voltages. A signal corresponding to an input signal is applied to the gates of a first p-channel MOS transistor and a first n-channel MOS transistor. A control circuit detects the falling edge of the input signal to create a first signal. A second p-channel MOS transistor is held in conduction by the first signal during a period beginning with the rising edge of the output signal and ending with the instant at which the output signal can be regarded as having logic high (H) level. The rising edge of the input signal is detected to create a second signal. A second n-channel MOS transistor is held in conduction by the second signal during a period beginning with the falling edge of the output signal and ending with the instant at which the output signal can be regarded as having logic low (L) level.
