Silicon Laboratories introduced the industry’s first drop-in replacement for optocouplers based on mainstream CMOS technology and incorporating an innovative light-emitting diode (LED) emulator input.

Ideally, an optical table’s vertical vibration response on isolators would be a single-degree-of-freedom system. The system would be symmetrical around the vertical axis, and a vertical force through ...

There is a common misconception that optocouplers will always fail with an “open” circuit when a high-voltage event breaks the device. Although there are many ways that an optocoupler can fail open, ...
