FCD 825/A/B/C/O
General Description The FCD825 series of optoisolators have a
npn silicon Planar photo
transistor and a GaAs diode 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 design flexibility.
