ABSTRACT:
An IC having inputs and outputs for a plurality of frequency bands from a high frequency band to a low frequency band is protected from electrostatic damage.A high-frequency section of the IC is provided with a protection circuit including diode-connected transistors connected by multiple stages. In addition, there are applied the transistors in which elements thereof are isolated by insulator that can prevent thyristor operation.
