LM339DR from Texas Instruments, in a SOIC-14. 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 | 1OUT | output | Open-collector output of comparator 1. Requires an external pull-up resistor to a positive supply. Sinks up to 16 mA typical; V(OL) ≤ 400 mV at 4 mA. |
| 2 | 2OUT | output | Open-collector output of comparator 2. Requires an external pull-up resistor to a positive supply. |
| 3 | VCC | power_in | Positive supply rail. Single supply 2 V to 36 V, or split supply ±1 V to ±18 V. |
| 4 | 2IN- | input | Inverting input of comparator 2. Common-mode input voltage range includes ground when operated from a single supply. |
| 5 | 2IN+ | input | Non-inverting input of comparator 2. Common-mode input voltage range includes ground when operated from a single supply. |
| 6 | 1IN- | input | Inverting input of comparator 1. Input bias current typically 25 nA. |
| 7 | 1IN+ | input | Non-inverting input of comparator 1. Common-mode input voltage range includes ground. |
| 8 | 3IN- | input | Inverting input of comparator 3. |
| 9 | 3IN+ | input | Non-inverting input of comparator 3. |
| 10 | 4IN- | input | Inverting input of comparator 4. |
| 11 | 4IN+ | input | Non-inverting input of comparator 4. |
| 12 | GND | power_in | Ground/negative supply rail. Tied to VEE in split-supply operation. |
| 13 | 4OUT | output | Open-collector output of comparator 4. Requires an external pull-up resistor. |
| 14 | 3OUT | output | Open-collector output of comparator 3. Requires an external pull-up resistor. |
