TLP281-4 FOUR CHANNEL OPTOCOUPLER IC

The TLP281-4 serves as a digital isolator, providing electrical isolation between two circuits. It accomplishes this by employing four miniature transformers, each coupled with an LED and a photodiode. When a digital signal is applied to the input side (LEDs), it illuminates the corresponding photodiodes on the output side, generating an electrically isolated replica of the input signal.
