Abstract

PURPOSE:To reduce the number of integrated circuit terminals and lines connected to external circuit and simplify the constitution of system by externally transmitting the information output generated in the integrated circuit by using less number of output terminals. CONSTITUTION:Signals from signal input terminals a and b in the integrated circuit are mixed by digital mixing by digital mixing circuit 7 and the output thus obtained is fed into the base of transister Tr9. The emitter of this Tr9 is connected to voltage dividing terminal f of the external connection terminals and the collector is connected to output terminal g through diode 10. Also, input terminal c in the integrated circuit is connected to the base of Tr13 through inverter 11 and resister 12 and, then, the emitter is connected to the power supply terminal d on the positive side and the collector is connected to the negative side power supply terminal e through resister 14 and 15. Furthermore, resister 17 and Tr15 are connected between terminals g.d and terminals g.e. With this constitution, two or more different kinds of output information produced in the integrated circuit can be outputted in multiple by means of the same output terminal at the same time.
