The 100Mbps data rate handles fast serial interfaces without timing margin issues. Propagation delay is a symmetrical 15.7ns max for both low-to-high and high-to-low transitions, with pulse-width distortion held to 5ns max — tight enough to keep duty-cycle errors under control for PWM signals. ## 85kV/µs CMTI — why it matters in motor drives Common-mode transient immunity of 85kV/µs minimum means the output won't glitch when fast-switching IGBTs or SiC MOSFETs slam the isolation barrier with high dV/dt. In an automotive traction inverter or on-board charger, this margin prevents false triggering on the controller side during PWM commutation events. ## Dual supply ranges for flexible rail assignment The integrated isolated power converter generates the secondary-side rail from the primary-side input, so no external isolated bias supply is needed. ## AEC-Q100 qualification and production status AEC-Q100 qualified for automotive applications, which covers the stress tests required for PPAP submission in Tier-1 programs. The 20-SOIC wide-body package (7.50mm width) provides the creepage distance needed for 5000Vrms reinforced insulation.","metaTitle":"ISOW7742QDFMRQ1 Automotive Quad-Channel Isolator, 100Mbps","metaDescription":"TI ISOW7742QDFMRQ1 automotive quad-channel digital isolator with integrated isolated power. 100Mbps data rate, 5000Vrms isolation, AEC-Q100, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"ISOW774x-Q1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Grade":"Automotive","Series":"ISOW774x-Q1","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"100Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Isolated Power":"Yes","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.97V ~ 3.63V, 4.5V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"2/2","Rise / Fall Time (Typ)":"2.5ns, 2.4ns","Supplier Device Package":"20-SOIC","Pulse Width Distortion (Max)":"5ns","Propagation Delay tpLH / tpHL (Max)":"15.7ns, 15.7ns","Common Mode Transient Immunity (Min)":"85kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.6","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.60000","currency":"USD"},{"qty":10,"price":"$9.74600","currency":"USD"},{"qty":25,"price":"$9.34240","currency":"USD"},{"qty":100,"price":"$8.23150","currency":"USD"},{"qty":250,"price":"$7.82752","currency":"USD"},{"qty":850,"price":"$7.32249","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/91cb7261c5dbd0cc15559a154f8267e8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ISOW7742QDFMRQ1 have integrated isolated power?","answer":"Yes, the ISOW7742QDFMRQ1 integrates the isolated DC-DC converter on-chip, so it generates its own secondary-side supply rail from the primary-side input.
