译码器系列（Decoderseries）

74 series of integrated circuits can be divided into six categories:

74 x (standard);

.74ls (low-power schottky);

.74s x (schottky);

(advanced low-power schottky);

.74as (advanced schottky);

.74f x (high speed).

In recent years, there have been 74 series of high-speed CMOS circuits, which can be divided into three categories:

. HC work level for COMS;

. HCT is the TTL working level, which can be used interchangeably with the 74LS series;

.hcu is applicable to CMOS circuits without buffers.

These 9 74 series of products, as long as the back number is the same, its logic function and the arrangement of the pin are the same. Different types of 74 series products can be selected according to different conditions and requirements

Is high frequency, low voltage, high current schottky diode characteristics different from the common diode, it is widely used in switching power supply, frequency converter, drive circuit, high frequency, low voltage, high current rectifier, stream, protection diode is used
