LM339PWR

Texas Instruments · Comparators · TSSOP-14

LM339PWR from Texas Instruments, in a TSSOP-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 2OUT output Open-collector output of comparator 2. Requires an external pull-up resistor to a positive supply; sinks current when the inverting input is above the non-inverting input.
2 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.
3 VCC power_in Positive supply pin. Single supply 2 V to 36 V, or split supplies ±1 V to ±18 V (referenced to GND).
4 1IN- input Inverting input of comparator 1. Common-mode range extends from GND to VCC-1.5 V.
5 1IN+ input Non-inverting input of comparator 1. Common-mode range extends from GND to VCC-1.5 V.
6 2IN- input Inverting input of comparator 2. Common-mode range extends from GND to VCC-1.5 V.
7 2IN+ input Non-inverting input of comparator 2. Common-mode range extends from GND to VCC-1.5 V.
8 3IN+ input Non-inverting input of comparator 3. Common-mode range extends from GND to VCC-1.5 V.
9 3IN- input Inverting input of comparator 3. Common-mode range extends from GND to VCC-1.5 V.
10 4IN+ input Non-inverting input of comparator 4. Common-mode range extends from GND to VCC-1.5 V.
11 4IN- input Inverting input of comparator 4. Common-mode range extends from GND to VCC-1.5 V.
12 GND power_in Ground / negative supply pin.
13 4OUT output Open-collector output of comparator 4. Requires an external pull-up resistor to a positive supply; sinks current when the inverting input is above the non-inverting input.
14 3OUT output Open-collector output of comparator 3. Requires an external pull-up resistor to a positive supply; sinks current when the inverting input is above the non-inverting input.
