It delivers 25 Mbps per channel — fast enough for Profibus, DeviceNet, and SPI-level isolation without the cost of a 150 Mbps part. The 2500 Vrms isolation rating is basic isolation, suited for non-mains applications or designs where the system already provides reinforced isolation elsewhere. Common-mode transient immunity (CMTI) is rated at 25 kV/µs minimum, which handles the fast switching edges in motor drives, inverters, and industrial power supplies without data corruption. ## Channel configuration and supply flexibility Three channels run from Side 1 to Side 2, one channel runs the opposite direction — a 3/1 split that matches many half-duplex bus interfaces or mixed-direction sensor links. No integrated DC-DC converter means you need an isolated power supply on the secondary side if the load requires it. ## Timing and signal integrity Propagation delay is 42 ns max in both directions, with pulse-width distortion held to 2.5 ns max. Rise and fall times are 2 ns typical — fast edges that keep the signal clean but also mean the PCB layout should treat the output traces as controlled-impedance lines if the trace length exceeds a few inches. The 125°C upper limit covers the hot spots near power stages and enclosures that see direct sun.","metaTitle":"TI ISO7241CDWG4 Digital Isolator, 25 Mbps, 2500 Vrms","metaDescription":"Texas Instruments ISO7241CDWG4 quad-channel digital isolator with capacitive coupling, 25 Mbps data rate, 2500 Vrms isolation, -40°C to 125°C, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Mfr":"Texas Instruments","Type":"General Purpose","Series":"-","Package":"Tube","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)","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 5.5V","Number of Channels":"4","Base Product Number":"ISO7241","Voltage - Isolation":"2500Vrms","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)":"2.5ns","Propagation Delay tpLH / tpHL (Max)":"42ns, 42ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$58.8000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ec48dd4d2a144297fc20727889bc3e0c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ISO7241CDWG4 and ISO7241C?","answer":"The ISO7241C is the same base device in a narrower 16-SOIC body (7.50 mm vs. the wide-body package of the ISO7241CDWG4). The wide-body version provides greater creepage distance for the same 2500 Vrms isolation rating, which can simplify PCB layout for high-voltage clearance requirements."},{"question":"Can ISO7241CDWG4 be used for SPI isolation?","answer":"Yes. The 25 Mbps data rate supports SPI clock rates up to 25 MHz, and the unidirectional channel configuration (3 channels one way, 1 the other) matches the typical SPI signal set (SCK, MOSI, MISO, and a chip-select). The 42 ns propagation delay adds about one clock cycle of latency at 25 MHz, which is acceptable for most SPI peripherals."},{"question":"What is the propagation delay of ISO7241CDWG4?","answer":"Maximum propagation delay is 42 ns for both rising and falling edges (tpLH and tpHL). Pulse-width distortion is limited to 2.5 ns max, so the output pulse width closely matches the input."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7241CDWG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7241CDWG4 when reusing this data.
