ISO6721QDWVRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC1 | power_in | Supply voltage input for input-side circuitry, operating range 1.71-1.89 V (1.8 V mode) or 2.25-5.5 V (2.5-5 V mode). |
| 2 | OUTA | output | Digital output for channel A, supports data rates to 50 Mbps with typical propagation delay of 11 ns. |
| 3 | INB | input | Digital input for channel B, accepts 0 to VCCI logic levels with switching thresholds at 0.3×VCCI (low) and 0.7×VCCI (high). |
| 4 | GND1 | power_in | Ground reference return for input-side circuitry. |
| 5 | GND2 | power_in | Ground reference return for output-side circuitry. |
| 6 | OUTB | output | Digital output for channel B, supports data rates to 50 Mbps with typical propagation delay of 11 ns. |
| 7 | INA | input | Digital input for channel A, accepts 0 to VCCI logic levels with switching thresholds at 0.3×VCCI (low) and 0.7×VCCI (high). |
| 8 | VCC2 | power_in | Supply voltage input for output-side circuitry, operating range 1.71-1.89 V (1.8 V mode) or 2.25-5.5 V (2.5-5 V mode). |
