It supports a data rate of 25 Mbps with typical rise/fall times of 1 ns, making it suitable for isolating SPI, UART, or general-purpose digital signals in industrial environments.
The 2 ns maximum pulse-width distortion keeps the duty cycle intact, which matters when you are passing PWM signals for motor control or encoder feedback. If you need to push past 25 Mbps, you would step up to a higher-speed isolator family; for most industrial sensor interfaces and PLC digital inputs, this is the sweet spot.
Isolation and immunity — 2500 Vrms and 25 kV/µs CMTI
Rated for 2500 Vrms isolation, this part covers basic insulation for mains-connected equipment in overvoltage category II environments. The 25 kV/µs minimum common-mode transient immunity means it will not glitch when a motor drive switches a high-voltage rail — a common failure point in optocoupler-based designs. Capacitive coupling gives it better long-term stability than optocouplers, with no LED degradation over temperature or time.
Housed in a standard 8-SOIC package (3.90 mm width), it is a drop-in footprint for many existing designs. No isolated power on chip, so you still need a separate DC-DC converter or an isolated module if the two sides do not share a common ground reference.
