LM339APWR from Texas Instruments, in a TSSOP-14. 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 2; open-drain output sinks current when negative input exceeds positive input, maximum sink current 20 mA. |
| 2 | OUT2 | output | Output of comparator 1; open-drain output sinks current when negative input exceeds positive input, maximum sink current 20 mA. |
| 3 | VCC | power_in | Positive power supply; recommended operating range 2 to 30V. |
| 4 | IN2- | input | Negative input of comparator 1; voltage range -0.3 to 36V absolute maximum, common-mode 0 to VCC-2V. |
| 5 | IN2+ | input | Positive input of comparator 1; voltage range -0.3 to 36V absolute maximum, common-mode 0 to VCC-2V. |
| 6 | IN1- | input | Negative input of comparator 2; voltage range -0.3 to 36V absolute maximum, common-mode 0 to VCC-2V. |
| 7 | IN1+ | input | Positive input of comparator 2; voltage range -0.3 to 36V absolute maximum, common-mode 0 to VCC-2V. |
| 8 | IN3- | input | Negative input of comparator 3; voltage range -0.3 to 36V absolute maximum, common-mode 0 to VCC-2V. |
| 9 | IN3+ | input | Positive input of comparator 3; voltage range -0.3 to 36V absolute maximum, common-mode 0 to VCC-2V. |
| 10 | IN4- | input | Negative input of comparator 4; voltage range -0.3 to 36V absolute maximum, common-mode 0 to VCC-2V. |
| 11 | IN4+ | input | Positive input of comparator 4; voltage range -0.3 to 36V absolute maximum, common-mode 0 to VCC-2V. |
| 12 | GND | power_in | Ground; negative power supply connection and reference for all voltage measurements. |
| 13 | OUT4 | output | Output of comparator 4; open-drain output sinks current when negative input exceeds positive input, maximum sink current 20 mA. |
| 14 | OUT3 | output | Output of comparator 3; open-drain output sinks current when negative input exceeds positive input, maximum sink current 20 mA. |
