That 3/1 ratio fits a common pattern: isolate three sensor or control signals into a single MCU receive line, or three PWM commands out with one feedback channel back. At 25 Mbps the part handles SPI clock rates up to 12.5 MHz (half-duplex) or full-duplex SPI at 25 Mbps, plus CAN FD at 5 Mbps with margin, and UART up to 3.125 Mbps. Propagation delay maxes at 45 ns each way, which is tight enough that a 25 Mbps SPI transaction finishes within one 40 ns clock period — no need to stretch the clock for isolation latency. Pulse-width distortion stays under 5 ns, so duty-cycle-sensitive signals like PWM or Manchester-encoded data don't accumulate timing error across the barrier. ## 125 °C and 25 kV/µs CMTI — built for the engine bay The common-mode transient immunity of 25 kV/µs minimum means it won't glitch when a nearby solenoid or IGBT switching event slams a fast voltage step across the barrier — a real failure mode in motor-drive and inverter environments. Rise and fall times are a tight 2 ns typical, keeping the output edges clean for the downstream logic without excessive ringing. ## Package and footprint Housed in a 16-pin SOIC with 7.50 mm body width — the wide-body variant that gives 8 mm creepage for reinforced isolation. Surface-mount only, so plan for reflow assembly. No isolated power on-chip; the output side needs its own supply rail (same 3.15 V to 5.5 V range). The 16-SOIC footprint is shared across the ISO7241 family, so swapping between speed or channel-config variants is a direct BOM drop-in. ## Lifecycle and sourcing posture That means no last-time-buy clock ticking — you can commit this part to a production BOM without building an obsolescence contingency.","metaTitle":"TI ISO7241CQDWRQ1 Digital Isolator, 25 Mbps, AEC-Q100","metaDescription":"Texas Instruments ISO7241CQDWRQ1 automotive-grade capacitive-coupling digital isolator. 4 channels, 25 Mbps data rate, 4000 Vpk isolation, -40 to 125 °C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Mfr":"Texas Instruments","Type":"General Purpose","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"25Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 5.5V","Number of Channels":"4","Base Product Number":"ISO7241","Voltage - Isolation":"4000Vpk","Operating Temperature":"-40°C~125°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2ns, 2ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"5ns","Propagation Delay tpLH / tpHL (Max)":"45ns, 45ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.9200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/68f29bb88243ac8aa8be23bb5b51a7c6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ISO7241CQDWRQ1 AEC-Q100 qualified?","answer":"Yes, the ISO7241CQDWRQ1 carries an Automotive, AEC-Q100 qualification, making it suitable for automotive-grade applications including under-hood and chassis-domain ECUs."},{"question":"What is a suitable replacement for ISO7241CQDWRQ1?","answer":"No official pin-compatible replacement is listed in the cross-reference.
