Description
The  ACPL-827  is  a  DC-input  dual  channel  full-pitch phototransistor  optocoupler  which  contains  two  light emitting  diode  optically  coupled  to  two  separate transistor. It is packaged in a 8-pin DIP package.
Likewise, the ACPL-847 is a DC-input quad channel full pitch  phototransistor  optocoupler  which  contains  four light  emitting  diode  optically  coupled  to  four  separate transistor. It is packaged in a 16-pin DIP package
