Optocouplers For The Hybrid Industry

By Steve Ching, Isolink, Inc.

The use of optocouplers in the hybrid in- dustry has generally lagged behind their appearance in nonhybrid fields. While most hybrid applications for optocouplers are limited to simple phototransistors, nonhybrid designers are producing circuits with state-of-the-art high-performance optocouplers in dual in-line packages.

These optocouplers offer design benefits and flexibility, including high speed, very low input current operation, high common mode rejection, high input to output insulation, logic compatible inputs and outputs, integrated line receiving functions, AC/DC to logic interfacing, and current loop and output and highrel/military applications.

Unfortunately, these readily available optocouplers are not always obtainable in hybrid-compatible form. Engineers themselves must design hybrid optocouplers from basic components each time designs require optocoupling. Download the complete white paper to learn more.
