LM339NSR from Texas Instruments, in a SOIC-14-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Open-drain output of comparator 2; sinks current (max 20 mA) when negative input voltage exceeds positive input voltage plus offset voltage. |
| 2 | OUT2 | output | Open-drain output of comparator 1; sinks current (max 20 mA) when negative input voltage exceeds positive input voltage plus offset voltage. |
| 3 | VCC | power_in | Positive power supply pin; accepts 2 to 30 volts for LM339 standard version. |
| 4 | IN2- | input | Negative input of comparator 1; accepts input voltage from 0 to VCC − 2 V over full operating temperature range. |
| 5 | IN2+ | input | Positive input of comparator 1; accepts input voltage from 0 to VCC − 2 V over full operating temperature range. |
| 6 | IN1- | input | Negative input of comparator 2; accepts input voltage from 0 to VCC − 2 V over full operating temperature range. |
| 7 | IN1+ | input | Positive input of comparator 2; accepts input voltage from 0 to VCC − 2 V over full operating temperature range. |
| 8 | IN3- | input | Negative input of comparator 3; accepts input voltage from 0 to VCC − 2 V over full operating temperature range. |
| 9 | IN3+ | input | Positive input of comparator 3; accepts input voltage from 0 to VCC − 2 V over full operating temperature range. |
| 10 | IN4- | input | Negative input of comparator 4; accepts input voltage from 0 to VCC − 2 V over full operating temperature range. |
| 11 | IN4+ | input | Positive input of comparator 4; accepts input voltage from 0 to VCC − 2 V over full operating temperature range. |
| 12 | GND | power_in | Ground reference and negative power supply connection; accepts current returns from all comparators and provides voltage reference for input circuits. |
| 13 | OUT4 | output | Open-drain output of comparator 4; sinks current (max 20 mA) when negative input voltage exceeds positive input voltage plus offset voltage. |
| 14 | OUT3 | output | Open-drain output of comparator 3; sinks current (max 20 mA) when negative input voltage exceeds positive input voltage plus offset voltage. |
