The 4/2 input-side/side-2 split (four inputs on side 1, two on side 2) suits mixed-direction signal isolation in industrial interfaces like SPI, UART, and general-purpose GPIO breakouts. At 25 Mbps the ADUM7642CRQZ handles fast serial buses like SPI at 20 MHz clock (half-duplex) or 25 Mbps parallel data streams without bit-rate bottleneck. The 50 ns max propagation delay (tPLH/tPHL) and 6 ns pulse-width distortion keep timing skew tight enough for most multi-channel isolators in motor-drive feedback and PLC backplanes. The 15 kV/µs common-mode transient immunity (CMTI) is the headline spec for inverter-fed environments: in a motor drive with IGBT switching edges exceeding 10 kV/µs, this rating ensures the output does not glitch when the ground plane jumps. ## Package and footprint: 20-SSOP / 20-QSOP No isolated power is generated on-chip — the part needs a separate isolated DC-DC converter for the secondary side if the two ground domains are fully separated. The ROHS3 compliance and MSL level (standard per iCoupler family) mean standard lead-free reflow profiles apply; no special bake is needed if the moisture-barrier bag is intact. ## Lifecycle and supply posture For dual-source planning, the ADUM7643CRQZ (same 6-channel count, 25 Mbps, but with 3/3 input-side/side-2 split) is a functional alternate if the direction assignment can be mirrored. The ADUM7640ARQZ (1 Mbps, 6/0 unidirectional) is a lower-speed drop-in for designs that do not need the 25 Mbps rate. Both are from the same iCoupler series and share the 20-SSOP footprint.","metaTitle":"ADUM7642CRQZ iCoupler Digital Isolator, 25 Mbps, 1000 Vrms","metaDescription":"ADI ADUM7642CRQZ general-purpose digital isolator: 25 Mbps data rate, 1000 Vrms isolation, 6 unidirectional channels, -40°C to 105°C.

The 50 ns propagation delay is acceptable for SPI clock rates up to roughly 10 MHz. For higher clock rates, verify timing margin against the specific SPI slave setup/hold requirements."},{"question":"Does the ADUM7642CRQZ support 25 Mbps data rate?","answer":"Yes, the ADUM7642CRQZ is rated for a data rate of 25 Mbps with typical rise/fall times of 2 ns and a max propagation delay of 50 ns."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM7642CRQZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM7642CRQZ when reusing this data.
