The TLP521, TLP521-2, and TLP521-4 series of optically coupled isolators are made up of twin in-line plastic packages that are both space-efficient and contain infrared light emitting diodes and NPN silicon phototransistors. Its a type of IC which has 16 Pins. Its a type of Phototransistor as we are already aware from the  phototransistor's working photo transistor is used to detect the light after detection of the light it converts the light in the digital signal. This diode is basically operated by the light signal instead of electrical signal. It has small size less costly highly reliable.

This IC contains four optocoupler in it Optocoupler  contains A photodiode and a BJT. like this It has 4 photodiode and 4 BJT. 

Applications:

  • Its used in computer terminal
