Application Based Optocoupler Design Guide
The Application Based Optocoupler Design Guide is the most comprehensive tool for selecting the proper Optocoupler to be used in CEL's focus applications. Not only do the block diagrams illustrate where the parts are used but also provides details on the selection criteria for each individual application. Then the reference table can be used to review basic specifications and help steer customers towards CEL's focus devices thus providing the quickest method for designing in the most competitive cost vs. performance devices at the point of design. From the guide itself, see how to best utilize the design guide:
