It supports a data rate of 25Mbps, which is fast enough for most SPI, UART, and general-purpose logic-level isolation tasks without the jitter or power penalty of optocouplers. The 42ns max propagation delay (both directions) and 2.5ns pulse-width distortion keep timing margins tight for synchronous interfaces. The supply range spans 3.15V to 5.5V, so it works on both 3.3V and 5V rails without a separate regulator — a practical advantage when the MCU side runs 3.3V and the field side is 5V. The 25kV/µs common-mode transient immunity (minimum) means it holds the barrier clean in motor-drive and inverter environments where fast switching edges couple into the isolation gap. The 16-SOIC wide-body (7.50mm width) footprint is common for high-voltage isolation parts, giving 8mm creepage between input and output sides — enough for basic reinforced isolation in 250Vrms working-voltage systems. For production BOMs that require a second-source option, the ISO7240 family includes pin-compatible variants with different channel counts and directionality — the ISO7241 (3/1) and ISO7242 (2/2) share the same 16-SOIC footprint and supply range, allowing a drop-in change without board re-spin if the channel configuration changes.","metaTitle":"TI ISO7240CFDWG4 Digital Isolator, 25Mbps, 2500Vrms, 16-SOIC","metaDescription":"Texas Instruments ISO7240CFDWG4 general-purpose digital isolator: 25Mbps data rate, 2500Vrms isolation, capacitive coupling, 4 unidirectional channels, -40°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":"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":"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":"$7.1000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ec48dd4d2a144297fc20727889bc3e0c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ISO7240CFDWG4 support 3.3V logic?","answer":"Yes, the supply range of 3.15V to 5.5V includes 3.3V logic levels on both sides of the isolation barrier."},{"question":"Can ISO7240CFDWG4 be used for SPI isolation?","answer":"Yes, the 25Mbps data rate and 42ns propagation delay are adequate for SPI clock rates up to about 12MHz with margin for setup/hold times.
