Abstract

PURPOSE:To enable to zero the excessive power consumption not in use, by operating the diode corresponding to the control switch turned on, feeding the reference voltage to the voltage to the respective constant current circuit, and operating the constant current source circuit. CONSTITUTION:The constant current source circuits 10-1...10-n and 20-1...20-n are driven with the respective control switches 30-1...30-n. Further, the negative terminal of the generation circuits 40 and 50 of the reference voltage Vs is connected to the control switches 30-1...30-n through the diodes D1...Dn, and the diode corresponding to the control switch turned on is operated, the reference voltage Vs is fed to the constant current circuit, and the constant current source circuit is operated. By using this semiconductor switch drive circuit as the telephone call element, the excessive power consumption not in use can be zeroed.
