The 150 Mbps data rate supports isolating fast serial links like SPI at 50 MHz or full-speed USB without introducing jitter. The 3750 Vrms isolation is the reinforced rating for mains-connected equipment — think motor drives, grid-tied inverters, or medical patient-contact interfaces. Common-mode transient immunity of 75 kV/µs means the part won't glitch when a nearby IGBT switches at high dV/dt, a common failure point in inverter and servo-drive designs. The 3 ns max pulse-width distortion keeps the duty cycle intact for PWM signals or timing-critical data, while the 13 ns max propagation delay sets the loop-closure budget for digital control loops — budget for it in your timing analysis. All four channels are unidirectional from side 1 to side 2, so plan your signal direction accordingly — this is a one-way barrier, not a bidirectional transceiver.
Package and footprint notes
Housed in a 16-pin SOIC wide-body (7.50 mm width) package, surface-mount only. The wide-body SOIC provides the creepage distance needed for 3750 Vrms isolation — don't substitute a narrow-body footprint. No isolated power on chip; you'll need separate isolated supplies for each side.
