ABSTRACT:
A semiconductor integrated circuit formed of a source coupled type logic circuit including a field effect transistor switching a circuit in response to an input signal and a current controlling circuit for controlling the input signal current connected in series between the input terminal and the gate of the field effect transistor. Since an element for limiting current is provided at the input, current is prevented from flowing into the circuit but the voltage of the input signal is sent to the circuit. As a result, the power consumption and the size of the circuit are reduced.
