LM393-DW from DOWO, in a DIP-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 | 1OUT | output | Output of comparator 1; the datasheet gives a minimum sink current of 6 mA (VO ≤ 1.5 V) and a maximum output short-circuit current (ISC) of 20 mA. |
| 2 | 1IN- | input | Inverting input of comparator 1; input common-mode voltage range is 0 V to VCC − 1.5 V at 25 °C (0 V to VCC − 2.0 V over the full temperature range). |
| 3 | 1IN+ | input | Non-inverting input of comparator 1; input common-mode voltage range is 0 V to VCC − 1.5 V at 25 °C (0 V to VCC − 2.0 V over the full temperature range). |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | 2IN+ | input | Non-inverting input of comparator 2; input common-mode voltage range is 0 V to VCC − 1.5 V at 25 °C (0 V to VCC − 2.0 V over the full temperature range). |
| 6 | 2IN- | input | Inverting input of comparator 2; input common-mode voltage range is 0 V to VCC − 1.5 V at 25 °C (0 V to VCC − 2.0 V over the full temperature range). |
| 7 | 2OUT | output | Output of comparator 2; the datasheet gives a minimum sink current of 6 mA (VO ≤ 1.5 V) and a maximum output short-circuit current (ISC) of 20 mA. |
| 8 | VCC | power_in | Positive supply; recommended operating range is 3 V to 32 V single-supply or ±16 V dual-supply, with absolute maximum 36 V or ±18 V. |
