# LTC393YS8

**Linearin** · Comparators · SOIC-8

LTC393YS8 from Linearin, 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 comparator output is open-drain, and the datasheet rates the output short-circuit condition as continuous. |
| 2 | -INA | input | Channel A negative input; the voltage range is from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 3 | +INA | input | Channel A positive input; it has the same voltage range as the negative input, (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 4 | -VS | power_in | Negative power supply, the reference for the input common-mode range (VS- - 0.1 V to VS+ + 0.1 V). |
| 5 | +INB | input | Channel B positive input; it has the same voltage range as the negative input, (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 6 | -INB | input | Channel B negative input; the voltage range is from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 7 | OUTB | output | Channel B comparator output is open-drain, and the datasheet rates the output short-circuit condition as continuous. |
| 8 | +VS | power_in | Positive power supply; the operating supply range is 1.8 V to 5.5 V (absolute maximum 10.0 V). |
