LM393SR 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 | Output of comparator 1, open-drain; connect to a load or pull-up resistor. |
| 2 | -IN1 | input | Inverting input of comparator 1; voltage range from -Vs -0.3V to +Vs +0.3V. |
| 3 | +IN1 | input | Non-inverting input of comparator 1; 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 with a 0.1μF capacitor placed as close as possible. |
| 5 | +IN2 | input | Non-inverting input of comparator 2; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V). |
| 6 | -IN2 | input | Inverting input of comparator 2; voltage range from -Vs -0.3V to +Vs +0.3V. |
| 7 | OUT2 | output | Output of comparator 2, open-drain; connect to a load or pull-up resistor. |
| 8 | +Vs | power_in | Positive power supply, 2V to 36V single supply; place a 0.1μF bypass capacitor as close to the part as possible. |
