# COS393SR

**COSINE** · Comparators · SOP-8

COS393SR from COSINE, 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 | OUT1 | output | Open-drain output of comparator 1, which must be connected to a load or pull-up resistor. |
| 2 | -IN1 | input | Inverting input of comparator 1, with a voltage range from -Vs -0.3V to +Vs + 0.3V. |
| 3 | +IN1 | input | Non-inverting input of comparator 1, with the same voltage range as -IN (-Vs -0.3V to +Vs + 0.3V). |
| 4 | -Vs | power_in | Negative power supply or ground; if not connected to ground, bypass it with a 0.1μF capacitor placed as close to the part as possible. |
| 5 | +IN2 | input | Non-inverting input of comparator 2, with the same voltage range as -IN (-Vs -0.3V to +Vs + 0.3V). |
| 6 | -IN2 | input | Inverting input of comparator 2, with a voltage range from -Vs -0.3V to +Vs + 0.3V. |
| 7 | OUT2 | output | Open-drain output of comparator 2, which must be connected to a load or pull-up resistor. |
| 8 | +Vs | power_in | Positive power supply (2V to 36V single supply), with a 0.1μF bypass capacitor placed as close to the part as possible. |

## CAD (KiCad official)

- Symbol: `COS393SR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `cos393sr-etched.step` / `cos393sr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cos393sr.step` / `cos393sr.glb` are the bare package body.
