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,
