**MSKSEMI** · Comparators · SOP-8

LMV393S-13 from MSKSEMI, in a SOP-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 comparator output; the datasheet notes the open-drain output allows the logic low level (VOL) to be set by the user with an external pull-up, and the output pulls up to 5.6 V max per the electrical characteristics. |
| 2 | -INA | input | Channel A inverting input; input voltage is limited to (V-) - 0.3 V to (V+) + 0.3 V and input current to ±10 mA per the absolute maximum ratings. |
| 3 | +INA | input | Channel A noninverting input; input voltage is limited to (V-) - 0.3 V to (V+) + 0.3 V and input current to ±10 mA per the absolute maximum ratings, with a common-mode range that includes ground. |
| 4 | V- | power_in | Negative (lowest) power supply; the datasheet specifies single-supply operation from 2.1 V to 5.5 V (V+ relative to V-) or dual supplies of ±0.9 V to ±2.75 V. |
| 5 | +INB | input | Channel B noninverting input; input voltage is limited to (V-) - 0.3 V to (V+) + 0.3 V and input current to ±10 mA per the absolute maximum ratings, with a common-mode range that includes ground. |
| 6 | -INB | input | Channel B inverting input; input voltage is limited to (V-) - 0.3 V to (V+) + 0.3 V and input current to ±10 mA per the absolute maximum ratings. |
| 7 | OUTB | output | Channel B open-drain comparator output; the datasheet notes the open-drain output allows the logic low level (VOL) to be set by the user with an external pull-up, and the output pulls up to 5.6 V max per the electrical characteristics. |
| 8 | V+ | power_in | Positive (highest) power supply; the supply voltage (V+) - (V-) is limited to 7 V absolute maximum and 2.1 V to 5.5 V recommended. |
