IL55B
PHOTODARLINGTON OPTOCOUPLER
FEATURES • High Collector-Emitter Breakdown Voltage— 80 V minimum • High Isolation Resistance, 1011 W Typical • Standard Plastic DIP Package • Underwriters Lab File #E52744 V D E • VDE 0884 Available with Option 1 DESCRIPTION The IL55B is an optically coupled isolator with a Gallium Arsenide infrared LED and a silicon 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.
