LM339N Quad Voltage Comparator IC – 14-Pin DIP

The LM339N is a quad voltage comparator IC containing four independent comparators in a 14-pin DIP package. Each comparator compares two input voltages and switches its output according to which voltage is higher.

It is used in voltage monitoring, threshold detection and sensor signal comparison circuits. The through-hole package fits compatible breadboards, IC sockets and PCBs.

Features:

• Part number: LM339N

• Four independent voltage comparators

• 14-pin DIP through-hole package

• Operating supply voltage: 2V to 30V

• Open-collector outputs

• Input common-mode voltage range includes ground

• Operating temperature range: 0°C to 70°C

• External pull-up resistors are needed to produce high output voltage levels
