A 14-leg electronic device is a commonly used electronic device, often referred to as an integrated circuit chip or IC chip. They are miniature circuit boards composed of a number of electronic components (such as transistors, capacitors, resistors, etc.), and realize the functions of a variety of circuits through the interconnection of different electronic components. 14-leg electronic components are widely used in electronic devices, such as computers, mobile phones, televisions, etc., and have an important position in the field of modern science and technology.
Their compact size, high efficiency and strong reliability make them an essential part of modern electronic equipment.
1. L339(a 14-pin patch element) is a voltage comparator chip.2. The LM339 integrated block is equipped with four independent voltage comparators, which are characterized by:1) The offset voltage is small, the typical value is 2mV;2) Wide power supply voltage range, single power supply is 2-36V, dual power supply voltage is ±1V-±18V;3) The internal resistance limit of the comparison signal source is wider;4) The common model circumference is very large, 0~ (Ucc-1.5V) Vo;5) The differential input voltage range is large, large enough to be equal to the power supply voltage;6) The output potential can be selected flexibly and conveniently.
The 14 pins are relays in the electrical switch
