**Texas Instruments** · Comparators · TSSOP-14

LMV339MTX 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 | OUT B | output | Output of comparator channel B. |
| 2 | OUT A | output | Output of comparator channel A. |
| 3 | V+ | power_in | Positive (highest) power supply; the recommended supply range is 2.7 V to 5 V. |
| 4 | -IN A | input | Inverting input of comparator channel A. |
| 5 | +IN A | input | Noninverting input of comparator channel A. |
| 6 | -IN B | input | Inverting input of comparator channel B. |
| 7 | +IN B | input | Noninverting input of comparator channel B. |
| 8 | -IN C | input | Inverting input of comparator channel C. |
| 9 | +IN C | input | Noninverting input of comparator channel C. |
| 10 | -IN D | input | Inverting input of comparator channel D. |
| 11 | +IN D | input | Noninverting input of comparator channel D. |
| 12 | V- | power_in | Negative (lowest) power supply; the datasheet test conditions use V- = 0 V. |
| 13 | OUT D | output | Output of comparator channel D. |
| 14 | OUT C | output | Output of comparator channel C. |
