RS393XM from Jiangsu RUNIC Tech, in a MSOP-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; it needs an external pull-up resistor to reach a logic-high level, and its output saturation voltage is typically 150 mV. |
| 2 | -INA | input | Channel A inverting input; the common-mode voltage range is (V-)-0.1 V to (V+)+0.1 V over -40°C to 125°C, and input signals beyond 0.3 V outside the supply rails should be current-limited to ±10 mA or less. |
| 3 | +INA | input | Channel A noninverting input; the common-mode voltage range is (V-)-0.1 V to (V+)+0.1 V over -40°C to 125°C, and input signals beyond 0.3 V outside the supply rails should be current-limited to ±10 mA or less. |
| 4 | V- | power_in | Negative (lowest) power supply; for single-supply use the device operates from 1.8 V to 5.5 V between V+ and V-, or from ±0.9 V to ±2.75 V in dual-supply configuration. |
| 5 | +INB | input | Channel B noninverting input; the common-mode voltage range is (V-)-0.1 V to (V+)+0.1 V over -40°C to 125°C, and input signals beyond 0.3 V outside the supply rails should be current-limited to ±10 mA or less. |
| 6 | -INB | input | Channel B inverting input; the common-mode voltage range is (V-)-0.1 V to (V+)+0.1 V over -40°C to 125°C, and input signals beyond 0.3 V outside the supply rails should be current-limited to ±10 mA or less. |
| 7 | OUTB | output | Channel B open-drain output; it needs an external pull-up resistor to reach a logic-high level, and its output saturation voltage is typically 150 mV. |
| 8 | V+ | power_in | Positive (highest) power supply; the device operates from 1.8 V to 5.5 V single-supply, with absolute maximum supply voltage of 7 V. |
