LM393AM from HGSEMI, 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 | Comparator 1 open-collector output; can be wired-AND with other open-collector outputs, low-level output voltage 150 mV typ at IOL=4mA. |
| 2 | IN1- | input | Comparator 1 inverting input; common-mode range 0 to Vcc-1.5V at 25°C and must not go negative by more than 0.3V. |
| 3 | IN1+ | input | Comparator 1 non-inverting input; common-mode range 0 to Vcc-1.5V at 25°C and may go to 30V without damage. |
| 4 | GND | power_in | Ground; input common-mode range includes GND, and split supplies are also possible. |
| 5 | IN2+ | input | Comparator 2 non-inverting input; common-mode range 0 to Vcc-1.5V at 25°C and may go to 30V without damage. |
| 6 | IN2- | input | Comparator 2 inverting input; common-mode range 0 to Vcc-1.5V at 25°C and must not go negative by more than 0.3V. |
| 7 | OUT2 | output | Comparator 2 open-collector output; can be wired-AND with other open-collector outputs, low-level output voltage 150 mV typ at IOL=4mA. |
| 8 | VCC | power_in | Positive supply; operates over a wide single-supply range with datasheet specs at 5V to 30V and supply current 0.8 mA typ at 5V. |
