数字集成电路有门电路,如非门(反相器)、与门、与非门、或门、或非门、异或门,还有其他的电路如触发器、计数器、锁存器、译码器等。数字集成电路通常用DIP封装,其外接电路一般有8脚、14脚、16脚、20脚、24脚;其中有两个脚接电源,其中一个是Vdd,接电源的正极;一个是Vss,接电源的负极。学习数字电路的最好方法是通过各种电路的实验、制作,进而认识和掌握它们的应用。从本期开始,将通过实验项目讲解,非门、与非门计数器等数字电路的应用。
Digital integrated circuits have gates, such as NOT gates (inverters), AND gates, NAND gates, OR gates, NOR gates, XOR gates, and other circuits such as flip-flops, counters, latches, Etc. Digital integrated circuits are usually DIP package, the external circuit is generally 8 feet, 14 feet, 16 feet, 20 feet, 24 feet; of which there are two feet connected to the power supply, one of them is Vdd, then the positive power supply; Then the negative power supply. The best way to learn digital circuits is to experiment with them and make them to understand and master their applications. From the beginning of this issue, through the experimental project to explain, non-door, NAND gate counter and other digital circuits.
