It provides 3750Vrms galvanic isolation between two supply domains, each operating from 2.25V to 3.6V. With a data rate of 2Mbps and a propagation delay of 180ns max, it fits isolated SPI, UART, or general-purpose logic interfaces where signal timing is not the tightest constraint — think motor-drive control signals, PLC I/O modules, or isolated sensor readouts in industrial environments. The 20-SSOP package (5.30mm body width) keeps the board footprint compact for multi-channel isolation banks. ## 3750Vrms isolation — what it buys you in practice The 3750Vrms isolation rating is a 1-minute withstand voltage per basic insulation requirements. That covers reinforced insulation for 250Vrms working voltage environments typical in industrial controls and medical equipment. The 25kV/µs minimum common-mode transient immunity (CMTI) means the isolator won't glitch when a motor drive switches a high-voltage bus — a real concern in noisy backplanes. If your design sees 400VAC drives or needs 5kVrms reinforced for medical (IEC 60601), you'd step up to a higher-rated iCoupler variant; this part is sized for the 250V working-voltage class. ## 2Mbps and 180ns propagation delay — is it fast enough? At 2Mbps, this part handles 1MHz SPI clocks comfortably (the 180ns delay adds about 0.18 bit-times at 1MHz — negligible for most register reads). For 10MHz SPI or full-speed UART above 1Mbaud, you'd want a faster isolator (e.g., the ADuM140x family at 90Mbps). The 2ns rise/fall time keeps signal edges clean enough for short PCB traces; the 8ns max pulse-width distortion means the duty cycle won't drift significantly across temperature. For isolated RS-485 at 250kbps or CAN at 1Mbps, this is a solid fit. ## Temperature range and environment The 125°C ceiling matches the hot-end of industrial temperature grade — no need for a separate high-temp variant. The ROHS3 compliance means it passes the latest EU restriction directives, which simplifies compliance for export assemblies.","metaTitle":"ADUM1241ARSZ-RL7 Digital Isolator, 3750Vrms, 2Mbps, 20-SSOP","metaDescription":"ADI ADUM1241ARSZ-RL7 iCoupler digital isolator: 3750Vrms isolation, 2Mbps data rate, 2 unidirectional channels, 20-SSOP.
