Claim Text:
1. A controller area network (CAN) transceiver circuit comprising a first switch section circuit, a second switch section circuit, a reception section circuit, a transmission section circuit, a power supply circuit, a CAN-low (CANL) line and a CAN-high (CANH) line, wherein: the first switch section circuit is connected between the power supply circuit and the transmission section circuit and the second switch section circuit is connected between the power supply circuit and the reception section circuit, the power supply circuit transmits logic data for controlling a waveform of an output of each of the switch section circuits to the first switch section circuit and the second switch section circuit, a message transmitted via the CANL line and the CANH line is expressed as a dominant level (high level) or a recessive level (low level) based on a predetermined voltage difference between the CANL line and the CANH line, the first switch section circuit includes n first switching circuits and the second switch section circuit includes m second switching circuits, and n is equal to or greater than 2.
