ABSTRACT:
There is provided a semiconductor integrated circuit including an output circuit having a first buffer section to which a first power supply voltage is applied and an input signal is supplied to amplify and output the input signal, and a second buffer section to which a second power supply voltage is applied and a signal output from said first buffer section is supplied to amplify and output the signal outside through an output terminal, a switching element which has two terminals respectively connected to said output terminal and a ground voltage terminal and receives a control signal to change a conductive resistance, and a bias circuit for receiving the input signal or a signal output from said first buffer section, generating a control signal, and supplying the control signal to said switching element to control the conductive resistance of said switching element so as not to allow a potential of said output terminal to exceed a predetermined value.
