LM393MM from HGSEMI, in a MSOP-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 | Channel 1 open-drain output; output saturation voltage typically 0.1V at IOL=4mA. |
| 2 | 1IN- | input | Channel 1 inverting input; common-mode range -0.3V to VCC, differential input up to ±18V absolute maximum. |
| 3 | 1IN+ | input | Channel 1 non-inverting input; common-mode range -0.3V to VCC, differential input up to ±18V absolute maximum. |
| 4 | VEE | power_in | Negative supply, ground in single-supply operation; dual-supply operation is up to ±16V. |
| 5 | 2IN+ | input | Channel 2 non-inverting input; common-mode range -0.3V to VCC, differential input up to ±18V absolute maximum. |
| 6 | 2IN- | input | Channel 2 inverting input; common-mode range -0.3V to VCC, differential input up to ±18V absolute maximum. |
| 7 | 2OUT | output | Channel 2 open-drain output; output saturation voltage typically 0.1V at IOL=4mA. |
| 8 | VCC | power_in | Positive supply, 2V to 32V single-supply operation (36V absolute maximum). |
