These devices isolate high-speed digital signals and offer performance, reliability, and flexibility advantages not available with optocoupler solutions. The Si87xx series is based on Silicon Labs proprietary CMOS isolation technology for low-power and high-speed operation and are resistant to the wear-out effects found in optocouplers that degrade performance with increasing temperature, forward current, and device age. As a result, the Si87xx series offer longer service life and SOIC-8, DIP8 dramatically higher reliability compared to optocouplers. Ordering options Open Collector Output include open collector output with and without integrated pull-up resistor with Output Enable and output enable options.
