The Si87xx isolators are pin-compatible, one-channel, drop-in replacements for popular optocouplers with data rates up to 15 Mbps. 
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 dramatically higher reliability compared to optocouplers. 
Ordering options include open collector output with and without integrated pull-up resistor and output enable options.
