Description
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.
Automotive Grade is available for certain part numbers. These products are built using automotive-specific flows at all steps in the manufacturing process to ensure the robustness and low defectivity required for automotive applications.
