Photocoupler
KPC514 * KPC524 * KPC544
These Photocouplers cosist of two Gallium Arsenide Infrared Emitting Diodes and a Silicon NPN Photo Darlington transistor perachannel. The KPC514 has one channel in a 4-pin package. The KPC524 has two channels in a 8-pin package. The KPC544 has four channels in a 16-pin package.
FEATURES
* Small Package Size * Collector-Emitter Voltage : Min.30V * Current Transfer Ratio : Type 1000% (at IF= 3/41mA, VCE=2V) * Electrical Isolation Voltage : AC2500Vrms * UL Recognized File No. E107486
APPLICATIONS
* AC Signal Input * Interface between two circuits of different potential * Automatic Vending Machine * Copiers, Industrial Robots
