Abstract

본 발명은 인버터 회로를 사용하지 않고 저전압 공급으로도 브이씨알 외부신호 절환시 브이씨알을 동작시킬 수 있게 하는 저전압을 이용한 브이씨알의 동작회로에 관한 것으로, Vcc단자에는 5V 전원이 입력되게 하고, VEE단자에는 저항(R7) (R8)을 통해 -7V 전원이 입력되게 하며, V 콘트를 단자에는 마이컴에서 출력되는 전원, 즉, 0V나 5V나 입력되게 하여 저전압으로도 브이씨알의 동작이 가능하도록 한 것이다.The present invention is directed to a circuit operation of the V-CR with a low voltage to a low voltage supply without the use of the inverter circuit is also able to operate the V CR for external signal switching V CR, V cc terminal to be 5V power is input, -7V power is input to the V EE terminal through a resistor (R 7 ) (R 8 ), and V control is input to the power output from the microcomputer, that is, 0V or 5V. This would be possible.
