It is a general-purpose part, meaning it handles standard digital signals — SPI, UART, GPIO, PWM — up to 25 Mbps without needing a dedicated protocol isolator. ## 25 Mbps data rate — what it buys you At 25 Mbps, this part comfortably handles 8-bit SPI at 25 MHz clock, UART at any common baud rate (115200, 1 Mbps, etc.), and general-purpose digital I/O. The 57 ns max propagation delay (both directions) and 4 ns pulse-width distortion mean the timing budget stays tight enough for most control and data-acquisition links. If you need 50 Mbps or higher, the family has faster siblings; for isolated I²C (bidirectional), this is not the right part — the unidirectional channels won't handle the clock stretching. ## 25 kV/µs CMTI — why it matters for motor drives and inverters Common-mode transient immunity of 25 kV/µs is the spec that keeps data intact when a motor-drive IGBT switches 600 V in a few nanoseconds. Without enough CMTI, the coupling capacitor inside the isolator can misinterpret the fast edge as a logic transition, corrupting the signal. This rating is well into the industrial inverter range and matches what you need for variable-frequency drives, servo amplifiers, and UPS systems. It is ROHS3 compliant.","metaTitle":"TI ISO7320FCD Digital Isolator, 25Mbps, 3000Vrms, 8-SOIC","metaDescription":"ISO7320FCD: TI general-purpose 2-channel capacitive isolator, 25Mbps data rate, 3000Vrms isolation, -40°C to 125°C, 8-SOIC.

The ISO7320FCD has both channels going from side 1 to side 2 (unidirectional), while the ISO7321FCD has one channel in each direction. Check your signal flow — if you need a reverse-direction channel, the ISO7321FCD is the correct choice."},{"question":"Can ISO7320FCD be used for I2C isolation?","answer":"No. The ISO7320FCD has two unidirectional channels (both from side 1 to side 2). I²C requires bidirectional data lines (SDA) and clock stretching, which this part cannot support. For isolated I²C, look at dedicated I²C isolators like the ISO1540 or ISO1541."},{"question":"Is ISO7320FCD compatible with 3.3V logic?","answer":"Yes. The inputs and outputs are referenced to their respective supply rails, making it a straightforward level translator as well as an isolator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7320FCD","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7320FCD when reusing this data.
