Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a photocoupler transmission circuit in which the malfunction of the photocoupler can be prevented even when noise is impressed to a transmission line while the output of a logic circuit is turned off. SOLUTION: While a 1st switching element 14 of a logic circuit 2 is turned off, a 2nd switching element 15 of the logic circuit 2 is turned on and a transmission line 3 is short-circuited.
