LM293PT from STMicroelectronics, in a TSSOP-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 | Output of comparator 1; open-collector style output, sink current typically 6 to 18 mA at Vid = 1 V, Vo = 1.5 V, with short-circuit current of approximately 20 mA max. |
| 2 | In1- | input | Inverting input of comparator 1; common-mode range 0 to (VCC+) - 1.5 V at 25 °C, input must not go below -0.3 V. |
| 3 | In1+ | input | Non-inverting input of comparator 1; common-mode range 0 to (VCC+) - 1.5 V at 25 °C, input must not go below -0.3 V. |
| 4 | Vcc- | power_in | Negative supply voltage (ground in single-supply operation); total supply (VCC+) - (VCC-) is 2 to 36 V. |
| 5 | In2+ | input | Non-inverting input of comparator 2; common-mode range 0 to (VCC+) - 1.5 V at 25 °C, input must not go below -0.3 V. |
| 6 | In2- | input | Inverting input of comparator 2; common-mode range 0 to (VCC+) - 1.5 V at 25 °C, input must not go below -0.3 V. |
| 7 | Out2 | output | Output of comparator 2; open-collector style output, sink current typically 6 to 18 mA at Vid = 1 V, Vo = 1.5 V, with short-circuit current of approximately 20 mA max. |
| 8 | Vcc+ | power_in | Positive supply voltage; total supply (VCC+) - (VCC-) is 2 to 36 V (abs max ±18 or 36 V). |
