Claims

[Scope of utility model registration request]

emitter-coupled first and second transistors, and resistors connected to the collectors of these transistors, respectively;
The first and second transistors have bases connected to collectors and collectors connected to emitters of the first and second transistors.
and third and fourth transistors of different conductivity types, the second transistor is supplied with a reference voltage, the first transistor is supplied with an input signal, and the first and second transistors are supplied with a reference voltage. The common emitters of the transistors are configured such that an input signal above the reference voltage level results in an output signal limited to the reference voltage level.
