Abstract

PURPOSE: To isolate and repair the shorted circuit portion after detection with a simple constitution, by inseting the switch circuit which cuts off the transistor when no address signal relating to the transistor is present in series with the transistor.
CONSTITUTION: To the AND gates 31,32...3n, the data signal inputted to the input terminals 11,12...1n and the address signal input inputted to the input terminal 1a are fed, and each output is outputted from the collector of Tr41,42...4n to the output circuits 51,52...5n. The series switch circuit Tr 400 which is connected in series with Tr41,42...4n and cuts off Tr when no address signal relating to Tr's is present, is provided. Thus, a failure taken place at one output system is not effected to other systems, the portion of short-circuit failure is detected with a simple circuit, and the failure part can be isolated and repaired.
