LP339MX

Texas Instruments · Comparators · SOIC-14

LP339MX from Texas Instruments, in a SOIC-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 OUTPUT 2 output Open-collector (uncommitted collector) output of comparator 2, which can sink 30 mA at VO=2 VDC and needs an external pull-up resistor.
2 OUTPUT 1 output Open-collector (uncommitted collector) output of comparator 1, which can sink 30 mA at VO=2 VDC and needs an external pull-up resistor.
3 V+ power_in Positive supply input, with supply voltage up to 36 VDC (absolute maximum) and operation from 2 VDC to 30 VDC; protected against reverse voltages.
4 INPUT 1 − input Inverting input of comparator 1 with a common-mode range from 0 V to V+−1.5 VDC at 25°C.
5 INPUT 1 + input Non-inverting input of comparator 1 with a common-mode range from 0 V to V+−1.5 VDC at 25°C.
6 INPUT 2 − input Inverting input of comparator 2 with a common-mode range from 0 V to V+−1.5 VDC at 25°C.
7 INPUT 2 + input Non-inverting input of comparator 2 with a common-mode range from 0 V to V+−1.5 VDC at 25°C.
8 INPUT 3 − input Inverting input of comparator 3 with a common-mode range from 0 V to V+−1.5 VDC at 25°C.
9 INPUT 3 + input Non-inverting input of comparator 3 with a common-mode range from 0 V to V+−1.5 VDC at 25°C.
10 INPUT 4 − input Inverting input of comparator 4 with a common-mode range from 0 V to V+−1.5 VDC at 25°C.
11 INPUT 4 + input Non-inverting input of comparator 4 with a common-mode range from 0 V to V+−1.5 VDC at 25°C.
12 GND power_in Ground (negative supply) pin; all pins of unused comparators should be tied to the negative supply.
13 OUTPUT 4 output Open-collector (uncommitted collector) output of comparator 4, which can sink 30 mA at VO=2 VDC and needs an external pull-up resistor.
14 OUTPUT 3 output Open-collector (uncommitted collector) output of comparator 3, which can sink 30 mA at VO=2 VDC and needs an external pull-up resistor.
