Si8711CC-IS isolators are pin-compatible, single-channel, drop-in optocoupler replacements with data rates up to 1 Mbps. The device isolates high-speed digital signals and offers performance, reliability, and flexibility advantages unavailable with optocoupler solutions. The Si8711CC-IS is based on our proprietary CMOS isolation technology for low-power and high-speed operation and is resistant to the wear-out effects found in optocouplers that degrade performance with increasing temperature, forward current, and device age. As a result, it offers longer service life and dramatically higher reliability compared to a traditional optocoupler.

Si871x SOIC8 LED Emulator Input Isolation Evaluation Kit

The Si871x evaluation kit eases evaluation of the performance of our Si87xx LED emulator input isolator in the 8-pin, SOIC package. The evaluation board is flexible enough to allow both hook-up to lab equipment for detailed spec evaluation as well as connection to an existing board. The evaluation board is jumper configurable for different device configurations and different drive schemes.
