The 8-SOIC package and surface-mount footprint fit standard assembly flows. Typical applications include isolating SPI, UART, or general-purpose digital signals in industrial fieldbus interfaces, motor-drive control logic, and isolated power-supply feedback paths where the environment demands industrial temperature tolerance (-40°C to 125°C). At 50 Mbps, this isolator can handle high-speed serial protocols like SPI at 25 MHz clock rates (full-duplex) or UART at several Mbps without introducing timing errors. The maximum propagation delay of 37 ns (both directions) and pulse-width distortion of 5 ns keep the signal integrity within budget for most industrial-grade interfaces. If your design runs a 50 MHz SPI clock or faster, you will need a higher-rate isolator; for typical 10–25 MHz SPI or asynchronous serial links, the 50 Mbps headroom is comfortable. ## Isolation and transient immunity for noisy environments Rated at 2500 Vrms isolation, the ISO7420FCCDR meets basic insulation requirements for industrial equipment with mains-voltage separation. The 25 kV/µs minimum common-mode transient immunity (CMTI) is the spec that matters when the isolator sits between a microcontroller and a motor-drive inverter or a switching power stage: fast voltage transients on the isolated side will not glitch the data output. This CMTI figure is competitive with optocouplers in the same isolation class, but without the LED aging and current-transfer-ratio drift that optocouplers exhibit over temperature and time. ## Channel direction and supply flexibility Both channels are forward-direction (Side 1 to Side 2), with no reverse channel. That means the part is a drop-in for isolating two downstream signals from a controller — for example, SPI clock and MOSI from an MCU to an isolated ADC. If you need a bidirectional channel (e.g., for a half-duplex RS-485 direction pin), you will need a part with a reverse channel or a separate isolator. ## Lifecycle and sourcing posture This part is ROHS3 compliant.","metaTitle":"TI ISO7420FCCDR Digital Isolator, 50 Mbps, 2-Ch, 8-SOIC","metaDescription":"Texas Instruments ISO7420FCCDR general-purpose digital isolator: 2500 Vrms isolation, 50 Mbps data rate, 2 unidirectional channels, -40°C to 125°C, 8-SOIC.","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":"50Mbps","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":"2.7V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"2/0","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"5ns","Propagation Delay tpLH / tpHL (Max)":"37ns, 37ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.12","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.12000","currency":"USD"},{"qty":10,"price":"$3.69800","currency":"USD"},{"qty":25,"price":"$3.49640","currency":"USD"},{"qty":100,"price":"$3.03020","currency":"USD"},{"qty":250,"price":"$2.87484","currency":"USD"},{"qty":500,"price":"$2.57958","currency":"USD"},{"qty":1000,"price":"$2.19900","currency":"USD"},{"qty":2500,"price":"$2.19900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/68c1208460ed8fc967eca5489d8d79cc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ISO7420FCCDR and ISO7420FEDR?","answer":"The ISO7420FEDR has faster propagation delay (11 ns vs 37 ns) and faster rise/fall times (1.8 ns / 1.7 ns vs 2.5 ns / 2.5 ns).
