4n32 Optocoupler Photo Darlington Opto Isolator Oscilloscope TM1638 8 Digit 7 SegmentDESCRIPTION The 4N32 and 4N33 are optically coupled isolators with a gallium arsenide infrared LED and a solicon photodarlington sensor. Switching can be achieved while maintaining a high degree of isolation between driving and load circuits. These optocouplers can be used to replace reed and mercury relays with advantages of long life, high speed switching and elimination of magnetic fields. FEATURES: Very high current transfer ratio, 500 % min. High
