Quad-channel isolation for industrial serial links
It is designed for general-purpose isolation of digital signals such as SPI, UART, and GPIO lines in industrial automation, motor drives, and power-conversion systems where a clean data path through a noisy ground plane is non-negotiable.
25 Mbps data rate — enough for most isolated serial links
At 25 Mbps, this part handles full-speed SPI (up to 25 MHz clock), standard UART baud rates well above 1 Mbps, and parallel GPIO updates without bit-rate headroom anxiety. The 42 ns max propagation delay (both directions) and 2.5 ns max pulse-width distortion keep the timing budget tight enough for most industrial backplane and sensor-interface designs.
25 kV/µs CMTI — the spec that keeps data clean in a motor drive
Common-mode transient immunity of 25 kV/µs minimum means this isolator will not glitch or latch when a fast-switching IGBT or SiC MOSFET slews the ground reference by hundreds of volts in a few nanoseconds. If your application is a variable-frequency drive, an inverter, or a switched-mode power supply, this CMTI rating is the one that separates a reliable link from a field-failure risk.
125°C operating temperature — rated for under-hood and industrial hot spots
A 105°C-rated isolator would be a downgrade for these environments.
