5 Summary

Optocouplers are a common design for achieving galvanic isolation for system signals. Light-emitting and light-sensitive components used to transmit signals inside of optocouplers are sensitive to temperature and time, so their performance can vary widely over operating temperature and time. Because of these components, optocouplers also tend to have slower response times, higher power consumption, and lower data rates. With semiconductor technological advances in recent decades, TI has developed opto-emulators with similar functionality as optocouplers and lower power consumption, improved CMTI and CTR, higher data rates and bandwidth, wider operating temperature ranges, and longer isolation lifetimes.
