ISO6721BQDRQ1 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 | Side-1 (input-side) supply pin; recommended VCC1 is 1.71 V to 1.89 V at 1.8 V operation or 2.25 V to 5.5 V at 2.5 V to 5 V operation, with absolute maximum VCC1-to-GND1 of -0.5 V to 6 V, and a 0.1 μF bypass capacitor should be placed as close to the pin as possible. |
| 2 | OUTA | output | Channel A output on the side-2 supply domain (ISO6721-Q1 D package); it is referenced to GND2 with absolute limits of -0.5 V to VCC2 + 0.5 V (not to exceed 6 V) and output current limited to ±15 mA. |
| 3 | INB | input | Channel B input on the side-1 supply domain (ISO6721-Q1 D package); it is referenced to GND1 with absolute limits of -0.5 V to VCC1 + 0.5 V (not to exceed 6 V), a logic-high threshold of 0.7 × VCCI and a logic-low threshold of 0.3 × VCCI, and supports data rates up to 50 Mbps. |
| 4 | GND1 | power_in | Ground reference for side 1 (VCC1 and the channel-B input circuitry); all side-1 voltages are measured relative to this pin. |
| 5 | GND2 | power_in | Ground reference for side 2 (VCC2 and the channel-A output circuitry); all side-2 voltages are measured relative to this pin, and it is isolated from GND1 by the isolation barrier. |
| 6 | OUTB | output | Channel B output on the side-2 supply domain (ISO6721-Q1 D package); it is referenced to GND2 with absolute limits of -0.5 V to VCC2 + 0.5 V (not to exceed 6 V) and output current limited to ±15 mA. |
| 7 | INA | input | Channel A input on the side-1 supply domain (ISO6721-Q1 D package); it is referenced to GND1 with absolute limits of -0.5 V to VCC1 + 0.5 V (not to exceed 6 V), a logic-high threshold of 0.7 × VCCI and a logic-low threshold of 0.3 × VCCI, and supports data rates up to 50 Mbps. |
| 8 | VCC2 | power_in | Side-2 (output-side) supply pin; recommended VCC2 is 1.71 V to 1.89 V at 1.8 V operation or 2.25 V to 5.5 V at 2.5 V to 5 V operation, with absolute maximum VCC2-to-GND2 of -0.5 V to 6 V, and a 0.1 μF bypass capacitor should be placed as close to the pin as possible. |
