ISO7310CQDRQ1 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 power supply, recommended operating range 3 V to 5.5 V. |
| 2 | IN | input | Logic input with TTL thresholds; recommended VIH is 2 V to 5.5 V and VIL is 0 V to 0.8 V. |
| 3 | VCC1 | power_in | Side-1 power supply, recommended operating range 3 V to 5.5 V. |
| 4 | GND1 | power_in | Ground connection for VCC1 (side-1 ground). |
| 5 | GND2 | power_in | Ground connection for VCC2 (side-2 ground). |
| 6 | OUT | output | Logic output; recommended IOH of -4 mA and IOL of 4 mA, with absolute maximum output current of ±15 mA. |
| 7 | GND2 | power_in | Ground connection for VCC2 (side-2 ground). |
| 8 | VCC2 | power_in | Side-2 power supply, recommended operating range 3 V to 5.5 V. |
