Function IC Series 74HC, 74LS Pin

Function IC 74HC, 74LS Plug

Both ICs and 74LS are IC standards (integrated circuits) of their 74, widely used in electronic applications. Here is the information about each type of IC:

Ic 74HC: 74HC is a high-speed CMOS IC (Complementary Metal-Oxide-Semiconductor) standard. It uses CMOS technology to provide low power consumption and workability with wide logical voltage. Code 74HC is usually followed by a letter OR number indicates the specific function of the IC, such as 74HC00 (NAND gate 4 inputs), 74HC32 (OR gate 4 inputs) and 74HC74 (Flip-flop D).

Ic 74LS: 74LS is a standard TTL IC (Transistor-Transistor Logic) with medium speed. It uses traditional TTL technology, providing good signal performance and high stability. Code 74LS is usually followed by a letter or number indicates the specific function of the IC, such as 74LS00 (NAND gate 4 inputs), 74LS86 (XOR gate 2 inputs) and 74LS138 (Decoder / Demultiplexer).

The main difference between 74HC and 74LS is in technology and specifications:

Technology: 74HC uses CMOS technology, while 74LS uses traditional TTL technology.
Energy Consumption: 74HC consumes lower energy than 74LS.
Speed: 74HC has higher speed than 74LS.
Logical voltage: 74HC is capable of working with wider logic voltage than 74LS.
The selection between 74HC and 74LS depends on the specific requirements of the application. 74hc is often preferred for use in applications requiring high speed and low power consumption, while 74LS is suitable for medium applications and requires TTL transmission compatibility. System.
