This is critical in motor-drive inverters, solar inverters, and any application where fast-switching power stages share a ground reference with the control side. The base product number ISO7221 covers a family of speed and channel-configuration variants, simplifying BOM consolidation if you need a different data rate or channel count in the same footprint. ## 8-SOIC package — board area and storage notes Housed in an 8-SOIC (0.154\", 3.90mm width) surface-mount package, this isolator fits standard SOIC-8 land patterns.","metaTitle":"TI ISO7221BDR Digital Isolator, 5Mbps, 2500Vrms, 8-SOIC","metaDescription":"Texas Instruments ISO7221BDR dual-channel digital isolator, 5Mbps data rate, 2500Vrms isolation, capacitive coupling, -40°C to 125°C, 8-SOIC.","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":"5Mbps","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":"3V ~ 5.5V","Number of Channels":"2","Base Product Number":"ISO7221","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C~125°C","Inputs - Side 1/Side 2":"1/1","Rise / Fall Time (Typ)":"1ns, 1ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"70ns, 70ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1712d03fe062b8dd6fd316c327e8b1ca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ISO7221BDR/alternatives.json"},"ai":{"faq":[{"question":"Does ISO7221BDR support 5Mbps?","answer":"Yes, the ISO7221BDR is rated for a maximum data rate of 5Mbps.

They are not pin-compatible for a drop-in replacement unless your circuit uses only one direction per channel.
