LM3302N

Texas Instruments · Comparators · PDIP-14

LM3302N from Texas Instruments, in a PDIP-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 OUT1 output Open-collector NPN output of comparator 2 (per the datasheet's pin table); it sinks current when the negative input is above the positive input plus offset, with absolute maximum output voltage -0.3 V to 28 V and output sink current 20 mA.
2 OUT2 output Open-collector NPN output of comparator 1 (per the datasheet's pin table); outputs may be tied together for wired-AND, with absolute maximum output voltage -0.3 V to 28 V and sink current 20 mA.
3 VCC power_in Positive supply pin; supply voltage VS = (V+) - (V-) is 2 V to 28 V, and the common-mode input range extends from ground to VCC - 1.5 V at 25°C (VCC - 2 V over -40°C to 85°C).
4 IN2- input Inverting input of comparator 1 (per the datasheet's pin table); input current is limited to -20 mA absolute maximum and input voltage to -0.3 V to 28 V.
5 IN2+ input Non-inverting input of comparator 1 (per the datasheet's pin table); input voltage range is -0.3 V to 28 V with input current limited to 20 mA.
6 IN1- input Inverting input of comparator 2 (per the datasheet's pin table); input current is limited to -20 mA absolute maximum and input voltage to -0.3 V to 28 V.
7 IN1+ input Non-inverting input of comparator 2 (per the datasheet's pin table); input voltage range is -0.3 V to 28 V with input current limited to 20 mA.
8 IN3- input Inverting input of comparator 3; input current is limited to -20 mA absolute maximum and input voltage to -0.3 V to 28 V.
9 IN3+ input Non-inverting input of comparator 3; input voltage range is -0.3 V to 28 V with input current limited to 20 mA.
10 IN4- input Inverting input of comparator 4; input current is limited to -20 mA absolute maximum and input voltage to -0.3 V to 28 V.
11 IN4+ input Non-inverting input of comparator 4; input voltage range is -0.3 V to 28 V with input current limited to 20 mA.
12 GND power_in Negative supply pin; in single-supply use it is tied to system ground, and no capacitor should be placed between this pin and system ground when no negative supply is used.
13 OUT4 output Open-collector NPN output of comparator 4; it sinks current when the negative input is above the positive input plus offset, with absolute maximum output voltage -0.3 V to 28 V and sink current 20 mA.
14 OUT3 output Open-collector NPN output of comparator 3; it sinks current when the negative input is above the positive input plus offset, with absolute maximum output voltage -0.3 V to 28 V and sink current 20 mA.
