Abstract
A signal input circuit having a CMOS inverter for receiving an input signal of a TTL level is disclosed. This circuit includes a first transistor of one channel type connected between a first power terminal and an output terminal and having a gate connected to an input terminal, a second transistor of an opposite channel type connected between a second power terminal and the output terminal and having a gate connected to the input terminal, and a current gain control circuit coupled to the first transistor for controlling the current gain of the first transistor to a first value when a power voltage is at a first level and to a second value when the power voltage is at a second level.
