A pulse-shaping circuit comprises a current limiter, which is connected in parallel with a voltage divider, for limiting a source voltage and enabling first and second voltage signals divided by the voltage divider to be constantly maintained, and an output voltage limiter which is provided to prevent a collector voltage of an output switching transistor from being increased to more than 0.1 V, so that an output pulse signal from an output terminal thereof may be lowered nearly to about 0.1 V when a low input pulse signal is applied to an input terminal thereof.
