LM293AM 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 | 1OUT | output | Channel 1 open-drain output, with typical low-level output voltage of 0.1V at IOL=4mA (max 0.4V). |
| 2 | 1IN- | input | Channel 1 inverting (negative) input, common-mode range 0 to VCC-1.5V. |
| 3 | 1IN+ | input | Channel 1 non-inverting (positive) input, common-mode range 0 to VCC-1.5V. |
| 4 | VEE | power_in | Negative supply, connected to GND in single-supply operation (dual-supply down to -16V). |
| 5 | 2IN+ | input | Channel 2 non-inverting (positive) input, common-mode range 0 to VCC-1.5V. |
| 6 | 2IN- | input | Channel 2 inverting (negative) input, common-mode range 0 to VCC-1.5V. |
| 7 | 2OUT | output | Channel 2 open-drain output, with typical low-level output voltage of 0.1V at IOL=4mA (max 0.4V). |
| 8 | VCC | power_in | Positive supply, 2V to 32V single supply (absolute maximum 36V). |
