10 MBd open-collector isolator for industrial and automotive signal paths
The open-collector output gives you the flexibility to pull up to any voltage within the supply range, which is useful when the receiving side runs at a different logic level than the optocoupler's own VCC.
20 kV/µs CMTI — keeps data clean in noisy environments
This is the spec that matters in motor-drive inverters, where the switching node jumps hundreds of volts in tens of nanoseconds. A part with lower CMTI would glitch and corrupt the feedback or gate-drive signal. The 100 ns maximum propagation delay (both tpLH and tpHL) keeps the loop response tight enough for most switching power supply feedback paths running below 500 kHz. If you need faster than that, you would step up to a digital isolator or a higher-speed optocoupler family.
125°C rating and wide supply — fits under-hood and industrial enclosures
The 2.7 V minimum supply means it will still operate during a cold-crank event down to 2.7 V, which is a common requirement for automotive ECUs.
