Last Update Time: 2019-01-18 17:08:30

There are many types of ICs, and the functions of different series of ICs are different. Even for the same series of ICs, the functions of different types have great differences. Therefore, in the use, it is necessary to pay attention to IC selection according to requirements, and must not be used at will.

 

The IC is a directional device. The arrangement of the IC pins is sequentially defined. The IC has a notch or a dot indicating the direction. The silkprint on the circuit board also has a notch or a dot mark. It will not be reversed. If it is reversed, it may cause the IC to burn out when it is used.IC pin polarity is shown in the figure below:

The pins of the IC should be close to the circuit board, The packaging material of the IC is very brittle. It should be handled gently when moving. Do not drop it on the floor to avoid damage.
