Abstract

PURPOSE: To transmit even when the one of transmitting lines is failed and is fixed to a certain fixed voltage by discharging a fixed current with working the one of the switching circuits of a transmitting circuit to have the two switching circuits corresponding to an input signal and constituting the other with a constant current circuit to suck the fixed current.
CONSTITUTION: A transmitting circuit 1 provides an inverter 5 and semiconductor switching components to work as a constant current circuit, a PNP type transistor Tr1 and an NPN type transistor Tr2, for instance. The respective other end of respective transmitting lines 7 and 8 of a transmitting channel 2 are connected to a receiving circuit 3, respectively, and a bias circuit 9 is connected to the input side of a receiving circuit 3 of the transmitting channel 2. When the input of an input terminal 1a becomes H, the output of the inverter 5 becomes L, bias voltage VCC1 is impressed on the base of the Tr1, a base current is supplied, the Tr1 is conducted, a fixed current I0 is discharged from a collector and is outputted to the transmitting line 7 through a diode D1. Besides, when the input of the input terminal 1a becomes H, the Tr2 is conducted, and the Tr2 sucks the fixed current I0 from the transmitting line 8 inversely to the Tr1, that is, a BUS (-) through a diode D2.
