Vishay”), disclaim any and all liability for any errors, inaccuracies or incompleteness contained in any datasheet or in any other disclosure . This datasheet presents five families of Vishay industry standard single channel phototransistor couplers. These families include the 4N, 4N3 4N3 4Ncouplers. They are also known as optoisolators since they separate two circuits optically.
These are used to couple two circuits without any ohmic contact.
They allow one of the circuits to switch another one while they are completely .
Meets or Exceeds all JEDEC Registered Specifications.
Optocoupler , Transistor Output, Channel, DIP, Pins, mA, kV, 1 . Also available in white package by specifying -M suffix, eg. There are different types of optocouplers but the functioning is very similar the 4Nis just one type and it is useful for hacking toys running on batteries or small power adapters etc. Industry standard dual-in-line package. Safety application model number covering all products in this datasheet is CNY17.
This model number should be used when consulting safety agency documents. In the case of the TTL output at the input of the optocoupler , the current should remain IOL ≤ mA. Using the diagram in the right . Opto lsolators for Standard Applications. Pin Opto Isolators - with Transistor Output. This is one possible way of using opto-coupler : PC817.
Particularly with the poor current transfer ratio of parts like these. So as you have already started to experiment and has been commented in other here the base resistor needs to be made . The optocoupler propagation delay is more . All digi- key links are provided for convenience only and are for example parts only. You can confirm by googling the part number and the word datasheet : LTV4Ndatasheet , and find the datasheet for the part. One of the pages in the datasheet will show the pinout: Pinout and Label.

The famous 4N(pins) and PC1(pins) part number can be easily used to substitute on many different types of Optoisolator IC part number.
Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators withstand .
