The 2 ns maximum pulse-width distortion keeps the duty cycle intact, which matters when you are passing PWM signals for motor control or encoder feedback. If you need to push past 25 Mbps, you would step up to a higher-speed isolator family; for most industrial sensor interfaces and PLC digital inputs, this is the sweet spot. ## Isolation and immunity — 2500 Vrms and 25 kV/µs CMTI Rated for 2500 Vrms isolation, this part covers basic insulation for mains-connected equipment in overvoltage category II environments. The 25 kV/µs minimum common-mode transient immunity means it will not glitch when a motor drive switches a high-voltage rail — a common failure point in optocoupler-based designs. Capacitive coupling gives it better long-term stability than optocouplers, with no LED degradation over temperature or time. Housed in a standard 8-SOIC package (3.90 mm width), it is a drop-in footprint for many existing designs. No isolated power on chip, so you still need a separate DC-DC converter or an isolated module if the two sides do not share a common ground reference.","metaTitle":"TI ISO7220CDR Digital Isolator, 25 Mbps, 2500 Vrms, 8-SOIC","metaDescription":"Texas Instruments ISO7220CDR general-purpose digital isolator: 25 Mbps data rate, 2500 Vrms isolation, capacitive coupling, 2 unidirectional channels, -40 to","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":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"2.8V ~ 5.5V","Number of Channels":"2","Base Product Number":"ISO7220","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C~125°C","Inputs - Side 1/Side 2":"2/0","Rise / Fall Time (Typ)":"1ns, 1ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"2ns","Propagation Delay tpLH / tpHL (Max)":"42ns, 42ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1712d03fe062b8dd6fd316c327e8b1ca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ISO7220CDR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between ISO7220 and ISO7220C?","answer":"The ISO7220C variant typically offers a wider operating temperature range or different isolation rating; the ISO7220CDR is the standard industrial-temperature (-40°C to 125°C) version in Tape & Reel.
