That matters when you're closing a control loop over an isolated SPI or UART link: the loop adds roughly 116ns of latency before the remote side sees the data. The 2.5ns rise and 2ns fall times (typical) keep edge rates fast enough that signal-integrity work on the PCB — trace length matching, termination — becomes the bottleneck, not the isolator. The ISO7310FCDR runs from 3V to 5.5V on both sides, so it works with 3.3V and 5V logic without a separate level shifter. ## Package and footprint — 8-SOIC reality The part comes in an 8-SOIC package (3.90mm body width), surface-mount only. The standard SOIC-8 footprint applies; no special land pattern needed. No isolated power on chip — the ISO7310FCDR is a signal-only isolator; the secondary side needs its own supply rail.","metaTitle":"TI ISO7310FCDR Digital Isolator, 3000Vrms, 25Mbps, 8-SOIC","metaDescription":"Texas Instruments ISO7310FCDR general-purpose digital isolator: 3000Vrms isolation, 25Mbps data rate, 25kV/µs CMTI, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","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":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"1","Voltage - Isolation":"3000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"1/0","Rise / Fall Time (Typ)":"2.5ns, 2ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"4ns","Propagation Delay tpLH / tpHL (Max)":"58ns, 58ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.85","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.85000","currency":"USD"},{"qty":10,"price":"$2.55900","currency":"USD"},{"qty":25,"price":"$2.41400","currency":"USD"},{"qty":100,"price":"$2.05690","currency":"USD"},{"qty":250,"price":"$1.93132","currency":"USD"},{"qty":500,"price":"$1.68990","currency":"USD"},{"qty":1000,"price":"$1.40021","currency":"USD"},{"qty":2500,"price":"$1.36650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3f4a39d2c6b59fd3a3eb0208deb0a051.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of ISO7310FCDR?","answer":"The maximum data rate is 25Mbps, with a propagation delay of 58ns max (tpLH / tpHL) and pulse-width distortion of 4ns max."},{"question":"Is ISO7310FCDR obsolete or discontinued?","answer":"There is no indication of discontinuation or last-time-buy."},{"question":"What are the alternatives to ISO7310FCDR?","answer":"Within the same family, the ISO7310FCDR is a unidirectional 1-channel device.
