Abstract
A semiconductor integrated noise absorbing circuit comprising an output variation detecting circuit for detecting such a condition that the output signal level of an output buffer circuit changes from a high level to a low level, an input level detecting circuit for detecting such a condition that a voltage level in high level of an input signal line, a capacitor connected to the input signal line, and a gate circuit connected between the load capacitor and the signal line, the gate circuit being closed so as to connect the capacitor to the input signal line if the voltage level of the input signal line is high when the output level of the output buffer circuit changes from a high level to a low level.
