Its 1 Mbps maximum data rate sets the ceiling for the serial interfaces it can isolate cleanly — think UART, low-speed SPI, or GPIO-level signals. For isolated SPI at higher clock rates (e.g., 10 MHz+), you would step up to a faster-rated iCoupler variant. Propagation delay is 75 ns max typ on both edges, with 25 ns pulse-width distortion, which is fine for most sensor readouts and configuration busses running under 1 MHz. ## 1000 Vrms isolation and 15 kV/µs CMTI — where it sits in the system Rated for 1000 Vrms isolation, this part handles basic functional isolation between low-voltage control domains and a separate power stage — think digital lines crossing an isolated DC/DC boundary or breaking ground loops in industrial sensor interfaces. The 15 kV/µs common-mode transient immunity (minimum) means it holds its state through fast switching edges, so it is a reasonable fit for motor-drive inverter legs or IGBT gate-driver feedback paths where noise couples across the barrier. The 3/1 input-to-output channel count gives you three channels driving from Side 1 to Side 2 and one reverse-direction channel, which maps neatly to a three-signal SPI (SCLK, MOSI, CS) plus a return MISO line. ## Package and footprint Surface-mount only — no through-hole option. The narrow body saves board area compared to a wider SOIC, but check your assembly house's capability for fine-pitch soldering; the 0.025\" (0.635 mm) pitch is standard for QSOP but may require a tighter stencil aperture than a standard SOIC. ## Lifecycle and compliance There is no LTB window to plan around.

The difference is the channel direction split: ADUM7441ARQZ has a 3/1 input-to-output configuration (three forward, one reverse), while the ADUM7442ARQZ-RL7 uses a 2/2 split.

The 3/1 channel count maps to SCLK, MOSI, and CS on Side 1 and MISO on Side 2. The 75 ns propagation delay and 25 ns pulse-width distortion are acceptable for most SPI transactions at this data rate. For faster SPI (10 MHz+), consider a higher-speed iCoupler variant with lower propagation delay."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM7441ARQZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM7441ARQZ when reusing this data.
