# LM293ADT

**STMicroelectronics** · Comparators · SO-8

LM293ADT from STMicroelectronics, in a SO-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 output, with 4 mA sink at 80 mV typ. and maximum output current of about 20 mA. |
| 2 | In1- | input | Comparator 1 inverting input; common-mode range is 0 V to (VCC+) - 1.5 V and it must not go below -0.3 V. |
| 3 | In1+ | input | Comparator 1 non-inverting input; common-mode range is 0 V to (VCC+) - 1.5 V and it must not go below -0.3 V. |
| 4 | Vcc- | power_in | Negative supply, or ground in single-supply operation; supply span (VCC+) - (VCC-) is 2 V to 36 V. |
| 5 | In2+ | input | Comparator 2 non-inverting input; common-mode range is 0 V to (VCC+) - 1.5 V and it must not go below -0.3 V. |
| 6 | In2- | input | Comparator 2 inverting input; common-mode range is 0 V to (VCC+) - 1.5 V and it must not go below -0.3 V. |
| 7 | Out2 | output | Comparator 2 output, with 4 mA sink at 80 mV typ. and maximum output current of about 20 mA. |
| 8 | Vcc+ | power_in | Positive supply, 2 V to 36 V single supply (or ±1 V to ±18 V split), with 0.45 mA typ. supply current at 5 V. |

## CAD (KiCad official)

- Symbol: `LM293ADT`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SO-8 (KiCad packages3D, STEP)
- 3D model files: `lm293adt-etched.step` / `lm293adt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm293adt.step` / `lm293adt.glb` are the bare package body.
