The device provides 5000 Vrms isolation voltage and a minimum common-mode transient immunity of 85 kV/µs, which is essential for maintaining signal integrity in the presence of fast-switching GaN or SiC power stages. The unidirectional channel configuration — three channels on side 1, one channel on side 2 — fits common SPI, UART, and GPIO isolation patterns where the primary-side microcontroller sends data across the barrier to a secondary-side peripheral. ## 100 Mbps signaling with tight timing margins With a maximum propagation delay of 16.5 ns and pulse-width distortion limited to 4.9 ns, the ISO7741EDWQ1 supports reliable data transmission at 100 Mbps. The 2.4 ns typical rise and fall times keep the signal edges clean enough for clocked interfaces like SPI at 50 MHz, though the 16.5 ns propagation delay means the designer should budget for that latency in the timing closure analysis — especially in daisy-chained isolation paths where delays accumulate. The device does not include an integrated isolated DC-DC converter, so a separate isolated power supply is required for the secondary side. ## Package and footprint for production assembly The wide SOIC footprint is a standard industry format for high-voltage isolators, so PCB layout reuse across multiple isolator vendors is straightforward. ## Lifecycle and sourcing posture For dual-sourcing flexibility, the base product number ISO7741 family includes multiple channel configurations and temperature grades — the E-grade suffix denotes the automotive -40°C to 150°C range, while the DWQ1 suffix specifies the 16-SOIC package with AEC-Q100 qualification.","metaTitle":"ISO7741EDWQ1 Automotive Quad-Channel Digital Isolator","metaDescription":"TI ISO7741EDWQ1 automotive AEC-Q100 quad-channel digital isolator, 100 Mbps, 5000 Vrms isolation, 85 kV/µs CMTI, -40°C to 150°C, 16-SOIC.","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":"Tube","Data Rate":"100Mbps","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":"2.25V ~ 5.5V","Number of Channels":"4","Base Product Number":"ISO7741","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C~150°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2.4ns, 2.4ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"4.9ns","Propagation Delay tpLH / tpHL (Max)":"16.5ns, 16.5ns","Common Mode Transient Immunity (Min)":"85kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0563a7f0bbcaef2753823ce64dfac017.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ISO7741 and ISO7740?","answer":"The ISO7741 provides a 3/1 channel configuration (three channels from side 1 to side 2, one channel from side 2 to side 1), while the ISO7740 offers a 4/0 configuration (all four channels unidirectional from side 1 to side 2).
