The 6N135 is an optocoupler with a GaAIAs infrared emitting diode, optically coupled with an integrated photo detector which consists of a photo diode and a high-speed transistor in a DIP8 plastic package. Signals can be transmitted between two electrically separated circuits up to frequencies of 2 MHz. The potential difference between the circuits to be coupled should not exceed the maximum permissible reference voltages.

Features of 6N135 Optocoupler:-

• TTL compatible
  
• High bit rates: 1 Mbit/s
  
• High common-mode interference immunity
  
• Bandwidth 2 MHz
