FCD820B - Fairchild Semiconductor

FCD820B Optically-Coupled Isolator

The FCD820 series of optoisolators combines a GaAs infrared-emitting diode and a silicon npn phototransistor in close proximity. Optical intercoupling provides a high degree of ac and dc isolation. A capability for continuous operation of the input diode results in a frequency response extending to dc. Connection to the transistor base is also provided for d.
