LP339DR

Texas Instruments · Comparators · SOIC-14

LP339DR 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 current when the inverting input is above the non-inverting input.
2 2OUT output Open-collector output of comparator 2. Requires an external pull-up resistor to a positive supply.
3 V+ power_in Positive supply voltage. Single-supply operation 2 V to 36 V or dual-supply ±1 V to ±18 V.
4 2IN- input Inverting input of comparator 2. Common-mode input range includes ground (V-).
5 2IN+ input Non-inverting input of comparator 2. Common-mode input range includes ground (V-).
6 1IN- input Inverting input of comparator 1. Common-mode input range includes ground (V-).
7 1IN+ input Non-inverting input of comparator 1. Common-mode input range includes ground (V-).
8 3IN+ input Non-inverting input of comparator 3. Common-mode input range includes ground (V-).
9 3IN- input Inverting input of comparator 3. Common-mode input range includes ground (V-).
10 4IN+ input Non-inverting input of comparator 4. Common-mode input range includes ground (V-).
11 4IN- input Inverting input of comparator 4. Common-mode input range includes ground (V-).
12 GND power_in Ground / negative supply (V-). Tie to system ground in single-supply operation, or to the negative rail in dual-supply operation.
13 4OUT output Open-collector output of comparator 4. Requires an external pull-up resistor to a positive supply.
14 3OUT output Open-collector output of comparator 3. Requires an external pull-up resistor to a positive supply.
