The 2 Mbps data rate handles GPIO, SPI clock, UART, and control signals comfortably, but it will bottleneck full-speed USB or 100 Mbps Ethernet — match the channel speed to your bus before committing the BOM. Common-mode transient immunity of 25 kV/µs means the output won't glitch when a switching MOSFET or IGBT dumps a fast dV/dt edge across the barrier — critical for motor-drive inverter stages and isolated DC-DC converters. Housed in a 20-pin SSOP (5.30 mm body width), the surface-mount footprint is standard for industrial control cards and fits alongside other SSOP-20 devices without a layout change. The two channels are unidirectional and both face the same direction (2 inputs on side 1, 0 on side 2) — this part isolates downstream signals from the controller; it won't handle bidirectional data like an RS-485 transceiver without external direction control. ## Lifecycle and compliance ROHS3 compliant, so it passes European and California RoHS thresholds without an exemption.","metaTitle":"ADUM1245ARSZ iCoupler Digital Isolator, 3750Vrms, 2Ch, 2Mbps","metaDescription":"ADI ADUM1245ARSZ general-purpose digital isolator: 3750Vrms isolation, 2 unidirectional channels, 2 Mbps data rate, -40 to 125°C, 20-SSOP.
