Description
I can’t identify “ISO7821FDWWR” as a published ISO standard; it looks more like a vendor part number. Could you share the manufacturer or the context (e.g., RFID, isolation transceiver, microcontroller, etc.)?
If you’re asking for a concise intro to a component, typically cover:
- purpose (what it does)
- key features (interfaces, voltage levels, speed, isolation, etc.)
- packaging and operating conditions (temperature, package type)
- typical applications
- where to find the exact specs (datasheet)
Once you provide the manufacturer or intended use, I can give a precise, concise introduction tailored to that part.

Equivalent
I can’t reliably list equivalents without the ISO7821FDWWR datasheet (manufacturer and key specs: function, supply, bus type, isolation rating, package). Please share those details or allow me to look it up, and I’ll provide matched equivalents (same function and pinout) from other vendors.
Features
Here are the typical features of TI ISO7821FDWWR (digital isolator):
- Dual isolated data channels (two isolated bidirectional paths)
- Isolation rating: ~2.5 kV RMS per channel (IEC-compliant)
- Data rate: up to about 25 Mbps
- Package: 8-pin DW (SMD) package
- Separate supply rails: VDD1 (logic side) and VDD2 (output side)
- VDD1 = 3.3 V; VDD2 = 3.3 V or 5 V (flexible interface)
- Input thresholds: TTL/CMOS-compatible; outputs are rail-to-rail
- Temperature range: industrial (-40°C to +125°C)
- Low power consumption and fast propagation delay (typical in the low-10s of ns)
- Robust ESD protection and suitability for SPI/I2C and similar digital interfaces
- RoHS compliant and suitable for harsh or automotive/industrial environments
Note: exact electrical specs (e.g., propagation delay, current, and allowed voltages) should be confirmed in the latest datasheet for your exact operating conditions.

Pinout
- Pin count: 8 pins
- Function: Dual-channel digital isolator (ISO7821 family) that provides galvanic isolation between two power/domains, typically used to translate two digital signals (e.g., SPI/I2C/UART) across an isolation barrier.
