ISO7321CQDQ1 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 | Power supply for the VCC1 (input) side; recommended supply range is 3 V to 5.5 V, and absolute maximum is 6 V. |
| 2 | OUTA | output | Output, channel A; recommended IOH of -4 mA and IOL of 4 mA. |
| 3 | INB | input | Input, channel B; VIH 2 V to 5.5 V and VIL 0 V to 0.8 V (TTL thresholds). |
| 4 | GND1 | power_in | Ground connection for VCC1. |
| 5 | GND2 | power_in | Ground connection for VCC2. |
| 6 | OUTB | output | Output, channel B; recommended IOH of -4 mA and IOL of 4 mA. |
| 7 | INA | input | Input, channel A; VIH 2 V to 5.5 V and VIL 0 V to 0.8 V (TTL thresholds). |
| 8 | VCC2 | power_in | Power supply for the VCC2 (output) side; recommended supply range is 3 V to 5.5 V, and absolute maximum is 6 V. |
