Hello Friends! I hope you are enjoying your life and having fun. Today, I am going to give you brief details on the Introduction to 6n137 . It is a photocoupler that is used to transfer electrical signal with the help of light between two separated circuits. It consists of one chip photo IC and high emitting diode. It is a 8 pin device which comes in DIP package. I'll try to cover as many aspects as possible related to this photocoupler. Let's get started. Introduction to 6n137 6n137 is a photocoupler also known as optocoupler that is used to connects the two electrically isolated circuits with the help of light. It consists of 8 pins where inputs and outputs terminals are electrically isolated which help in controlling the large power, current and AC voltages with small digital signal. It ...
