That speed comfortably covers SPI clocks up to 25 MHz, UART at any baud rate, and general-purpose isolated GPIO or control signals. Propagation delay is 42 ns max (tpLH / tpHL), with pulse-width distortion held to 2.5 ns max — tight enough to keep the duty cycle intact for PWM or timing-sensitive links. Rise and fall times are 2 ns typical, so the edges are clean without excessive ringing if you follow the usual 0.1 µF decoupling per supply pair. The supply range spans 3.15 V to 5.5 V on both sides, so the same device can sit between a 3.3 V MCU and a 5 V peripheral without a separate level translator. Just tie each side's VCC to its respective rail — the capacitive coupling handles the level shift internally. The 2500 Vrms isolation rating is the standard for basic/reinforced isolation in motor drives, industrial PSUs, and medical equipment. Common-mode transient immunity is a minimum 25 kV/µs, which keeps the output from glitching during fast switching events on the isolated side.","metaTitle":"Texas Instruments ISO7240CFDWR Digital Isolator, 25Mbps","metaDescription":"TI ISO7240CFDWR general-purpose digital isolator: capacitive coupling, 25Mbps data rate, 2500Vrms isolation, 3.15V-5.5V supply, -40°C 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":"-","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":"ISO7240","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C~125°C","Inputs - Side 1/Side 2":"4/0","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":"$6.0800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ec48dd4d2a144297fc20727889bc3e0c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the differences between ISO7240CFDWR and ISO7240CFDW?","answer":"The difference is the packaging format.
