LM393DRG from HANSCHIP semiconductor, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OUT | output | Comparator 1 open-collector output. Requires an external pull-up resistor to VCC (typ. 1 kΩ-100 kΩ). Sinks up to ~16 mA when the output is low. |
| 2 | 1IN- | input | Comparator 1 inverting input. When V(1IN-) > V(1IN+), the open-collector output pulls low. |
| 3 | 1IN+ | input | Comparator 1 non-inverting input. Common-mode input range extends from GND to VCC−1.5 V. |
| 4 | GND | power_in | Negative supply / ground reference. Tied to system ground in single-supply operation, or to V- in split-supply operation. |
| 5 | 2IN+ | input | Comparator 2 non-inverting input. Common-mode input range extends from GND to VCC−1.5 V. |
| 6 | 2IN- | input | Comparator 2 inverting input. When V(2IN-) > V(2IN+), the open-collector output pulls low. |
| 7 | 2OUT | output | Comparator 2 open-collector output. Requires an external pull-up resistor to VCC. Sinks up to ~16 mA when low. |
| 8 | VCC | power_in | Positive supply pin. Single-supply range 2 V to 36 V, or split-supply ±1 V to ±18 V. Decouple with a 0.1 µF ceramic capacitor to GND. |
