Overview: Si873x Data Sheet Low Input Current LED Emulator, Logic Output Isolators
The Si873x 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 Si873x 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 Si873x series offer longer service life and dramatically higher reliability compared to optocouplers. Ordering options include logic output with and without output enable options.
