Description
The Si871x/2x isolators are pin-compatible, single-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 Si871x/2x 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 Si871x/2x series offer longer service life and
dramatically higher reliability compared to optocouplers. Ordering options
include logic output with and without output enable options.
