A signal input circuit of a type in which an input signal voltage is compared with a reference voltage is disclosed. A first gate is connected in series with a first input transistor between a first terminal of an input amplifier comprising a flip-flop circuit and a reference terminal. A second gate is connected in series with a second input transistor between a second terminal of the input amplifier and the reference terminal. The first and second gates are controlled by potentials at third and fourth terminals of the input amplifier. The input terminals of an output amplifier are coupled to the first and second terminals of the input amplifier to provide output signals.
