LM239PWR

Texas Instruments · Comparators · TSSOP-14

LM239PWR 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 1OUT output Comparator 1 open-collector output. Requires an external pull-up resistor to a positive supply (typ. 3 kΩ-15 kΩ to VCC).
2 2OUT output Comparator 2 open-collector output. Requires an external pull-up resistor to a positive supply.
3 VCC power_in Positive supply voltage. Single-supply range 2 V to 36 V, or split-supply ±1 V to ±18 V. Absolute max 36 V (single) / ±18 V (dual).
4 2IN- input Comparator 2 inverting input. Common-mode input voltage range includes ground (0 V) up to VCC−1.5 V.
5 2IN+ input Comparator 2 non-inverting input. Common-mode input voltage range includes ground (0 V) up to VCC−1.5 V.
6 1IN- input Comparator 1 inverting input. Common-mode input voltage range includes ground (0 V) up to VCC−1.5 V.
7 1IN+ input Comparator 1 non-inverting input. Common-mode input voltage range includes ground (0 V) up to VCC−1.5 V.
8 3IN+ input Comparator 3 non-inverting input. Common-mode input voltage range includes ground (0 V) up to VCC−1.5 V.
9 3IN- input Comparator 3 inverting input. Common-mode input voltage range includes ground (0 V) up to VCC−1.5 V.
10 4IN+ input Comparator 4 non-inverting input. Common-mode input voltage range includes ground (0 V) up to VCC−1.5 V.
11 4IN- input Comparator 4 inverting input. Common-mode input voltage range includes ground (0 V) up to VCC−1.5 V.
12 GND power_in Ground / negative supply reference. Tied to 0 V in single-supply operation or to the negative rail in split-supply operation.
13 4OUT output Comparator 4 open-collector output. Requires an external pull-up resistor to a positive supply.
14 3OUT output Comparator 3 open-collector output. Requires an external pull-up resistor to a positive supply.
