    Hello,


    I do not understand the problem with circuit. When I am giving the in put voltage to AND gate as 12V the circuit is working. But the AND has voltage range of 5V only. So, what I need to do now. I am attaching the circuit with this
    post.


    Thanks & regards,
    Vivek Alaparthi

    I do not get the problem...If it's working, what do you presume is the problem?
    Is it AND gate works at 5v but you push it with an extra 7 and doesn't fry/it defy's manufacturer's specs...is that it?
    From the circuit, I presume the 5 at V1 source stands for the source voltage. As such, your circuit is perfectly fine. Your AND gates are sourcing from V1 but not v1+v2.

    Hello ,

    The circuit is not working and I think the feedback must be given to diode.

    Can you please help me , how to fix this?



    Thanks in advance,
