RS393XK-Q1 from Jiangsu RUNIC Tech, 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 | OUTA | output | Channel A open-drain output, which needs an external pull-up resistor to the logic supply and has a short-circuit duration limit of 10 s to V- or V+. |
| 2 | -INA | input | Inverting input of channel A; input pin voltage is rated (V-)-0.3 V to (V+)+0.3 V, and input signals swinging more than 0.3 V beyond the rails should be limited to ±10 mA. |
| 3 | +INA | input | Noninverting input of channel A; input common-mode range is (V-)-0.1 V to (V+)+0.1 V over the full temperature range, with the same ±10 mA current limit beyond the rails. |
| 4 | V- | power_in | Negative (lowest) power supply pin; single-supply operation is referenced to this pin, with the total supply (V+) - (V-) rated 1.8 V to 5.5 V. |
| 5 | +INB | input | Noninverting input of channel B; input common-mode range is (V-)-0.1 V to (V+)+0.1 V over the full temperature range, with the same ±10 mA current limit beyond the rails. |
| 6 | -INB | input | Inverting input of channel B; input pin voltage is rated (V-)-0.3 V to (V+)+0.3 V, and input signals swinging more than 0.3 V beyond the rails should be limited to ±10 mA. |
| 7 | OUTB | output | Channel B open-drain output, which needs an external pull-up resistor to the logic supply and has a short-circuit duration limit of 10 s to V- or V+. |
| 8 | V+ | power_in | Positive (highest) power supply pin; the supply is rated 1.8 V to 5.5 V single-supply, with absolute maximum supply voltage of 7 V. |
