Si873x Data Sheet Low Input Current LED Emulator, Logic Output Isolators KEY FEATURES The Si873x isolators are pin-compatible, single-channel, drop-in replacements for pop- ular optocouplers with data rates up to 15 Mbps. These devices isolate high-speed High Speed: dc to 15 Mbps digital signals and offer performance, reliability, and flexibility advantages not available 2.5 to 5.5 V logic output with optocoupler solutions. The Si873x series is based on Skyworks proprietary CMOS Pin-compatible, drop-in upgrades for isolation technology for low-power and high-speed operation and are resistant to the popular high-speed digital optocouplers wear-out effects found in optocouplers that degrade performance with increasing tem- Performance and reliability advantages vs. perature, forward current, and device age. As a result, the Si873x series offer longer optocouplers: service life and dramatically higher reliability compared to optocouplers.
