Abstract

See full text

An electronic circuit including an output circuit capable of reducing breakage while satisfying the characteristics of an output signal is provided. For this purpose, the electronic circuit includes output signal generation elements 201 and 202 configured to generate an output signal, switches 203 and 204, and a voltage monitor circuit 205 configured to monitor a voltage applied to an output terminal 112. Here, the output signal generation elements 201 and 202 are connected to the output terminal 112 via the switches 203 and 204, and the voltage monitor circuit 205 is configured to be able to measure a voltage higher than a power supply voltage VDD connected to the output signal generation element 201 and controls the switches 203 and 204 so as to disconnect the output signal generation elements 201 and 202 and the output terminal 112 when the voltage of the output terminal 112 becomes equal to or higher than a predetermined value set higher than the power supply voltage VDD.
