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.
