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.
