Its 25 Mbps data rate and 42 ns max propagation delay suit it for isolating SPI, UART, and general-purpose logic-level interfaces in motor drives, PLC I/O modules, and industrial fieldbus nodes. ## 25 Mbps with 42 ns propagation delay — timing budget for isolated links At 25 Mbps the part handles a 40 ns bit period, and the 42 ns max propagation delay (tpLH / tpHL) means the total loop delay for a single direction is just over one bit time. That matters for SPI clock rates above 10 MHz where the master expects data back within a half-cycle — the designer needs to account for the isolator delay in the timing closure. The 2.5 ns max pulse-width distortion keeps the duty-cycle error small enough for UART framing at 115200 baud without bit-slip. ## 2500 Vrms isolation and 25 kV/µs CMTI — noise rejection in harsh environments Rated for 2500 Vrms basic isolation per the device class, with a minimum common-mode transient immunity of 25 kV/µs. That CMTI figure is the key spec for motor-drive applications where the inverter switching generates fast common-mode voltage swings on the bus — if the isolator cannot reject those edges, data corrupts. The 2 ns typical rise/fall time keeps the output edges clean enough for the downstream logic without excessive ringing. ## Channel configuration: three inputs on side 1, one on side 2 The channel direction map is 3/1 — three channels drive from side 1 to side 2, one channel drives from side 2 to side 1. That asymmetric layout fits the common industrial pattern where a microcontroller on side 1 sends multiple control signals (chip select, clock, data) across the barrier and receives a single feedback or data-ready signal back. The unidirectional channel type means each channel is fixed-direction, so the designer must match the signal flow to the pin assignment before layout. ## Active lifecycle — no near-term obsolescence pressure It is a current-production part from Texas Instruments, and the wide supply range and industrial temperature grade mean it is specified into ongoing designs, not just legacy maintenance.","metaTitle":"TI ISO7241CDWRG4 Quad-Channel Digital Isolator, 25 Mbps","metaDescription":"Texas Instruments ISO7241CDWRG4 quad-channel digital isolator with capacitive coupling, 25 Mbps data rate, 2500 Vrms isolation, -40°C to 125°C range.","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":"Tape & Reel (TR)","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":"$4.2400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ec48dd4d2a144297fc20727889bc3e0c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ISO7241CDWRG4 obsolete or nearing end-of-life?","answer":"It remains a current-production TI part suitable for new designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7241CDWRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7241CDWRG4 when reusing this data.
