LP339MX from Texas Instruments, in a SOIC-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 | OUTPUT 2 | output | Open-collector (uncommitted collector) output of comparator 2, which can sink 30 mA at VO=2 VDC and needs an external pull-up resistor. |
| 2 | OUTPUT 1 | output | Open-collector (uncommitted collector) output of comparator 1, which can sink 30 mA at VO=2 VDC and needs an external pull-up resistor. |
| 3 | V+ | power_in | Positive supply input, with supply voltage up to 36 VDC (absolute maximum) and operation from 2 VDC to 30 VDC; protected against reverse voltages. |
| 4 | INPUT 1 − | input | Inverting input of comparator 1 with a common-mode range from 0 V to V+−1.5 VDC at 25°C. |
| 5 | INPUT 1 + | input | Non-inverting input of comparator 1 with a common-mode range from 0 V to V+−1.5 VDC at 25°C. |
| 6 | INPUT 2 − | input | Inverting input of comparator 2 with a common-mode range from 0 V to V+−1.5 VDC at 25°C. |
| 7 | INPUT 2 + | input | Non-inverting input of comparator 2 with a common-mode range from 0 V to V+−1.5 VDC at 25°C. |
| 8 | INPUT 3 − | input | Inverting input of comparator 3 with a common-mode range from 0 V to V+−1.5 VDC at 25°C. |
| 9 | INPUT 3 + | input | Non-inverting input of comparator 3 with a common-mode range from 0 V to V+−1.5 VDC at 25°C. |
| 10 | INPUT 4 − | input | Inverting input of comparator 4 with a common-mode range from 0 V to V+−1.5 VDC at 25°C. |
| 11 | INPUT 4 + | input | Non-inverting input of comparator 4 with a common-mode range from 0 V to V+−1.5 VDC at 25°C. |
| 12 | GND | power_in | Ground (negative supply) pin; all pins of unused comparators should be tied to the negative supply. |
| 13 | OUTPUT 4 | output | Open-collector (uncommitted collector) output of comparator 4, which can sink 30 mA at VO=2 VDC and needs an external pull-up resistor. |
| 14 | OUTPUT 3 | output | Open-collector (uncommitted collector) output of comparator 3, which can sink 30 mA at VO=2 VDC and needs an external pull-up resistor. |
