Abstract
A transmission apparatus includes a logic circuit for performing a predetermined process, and outputting a logic output signal depending on the process, an open-drain signal generation circuit, connectable at an input terminal to the logic circuit and at an output terminal to a pull-up resistor, and a transmission path failure determination circuit for determining whether there is a failure in a transmission path which transmits a signal outputted from the logic circuit via the open-drain signal generation circuit, wherein the transmission path failure determination circuit includes an edge waveform information obtaining circuit for obtaining edge waveform information indicating a waveform of at least one of a rising edge and a falling edge of an application signal, and a failure determination circuit for determining whether the edge waveform information satisfies a predetermined condition, and outputting a failure signal indicating that there is a failure in the transmission path.
