Texas Instruments TLC374CNS's Category - Comparator
Nearly every quantity that needs to be measured has a corresponding tool, and voltage measurement is no exception. For a comparator, the key lies in its name, as a comparator is designed to receive two voltages and tell the user which voltage is the highest.
The principle and design of a comparator are very simple: two currents pass through the comparator, they are read, and then the output indicates which current has the highest voltage. The current inputs to the comparator are the inverting input and the non-inverting input.
This can also be called the negative input and the positive input, where the inverting input is the negative input and the non-inverting input is the positive input. The output of the comparator will read high or low depending on which voltage current is the highest. A high level indicates a positive voltage current and a low level indicates a negative voltage current. These readings can also be represented in binary, with 0 representing a low or negative voltage and 1 representing a high or positive voltage. The output of the comparator can also be expressed by the following formulas: when V+ > V-, Vo = 1; when V+ < V-, Vo = 0.
A comparator works by amplifying the voltage difference between the two inputs, so as to better read the strongest voltage current and generate an output. The device that performs the amplification is called a high-gain differential amplifier. More details: What is a Comparator IC?
Manufacturer of TLC374CNS - Texas Instruments
TI is an international semiconductor company in the United States, headquartered in Dallas, Texas. The company was established in 1930 and has more than 100 offices worldwide, with more than 43,000 employees in the United States, Europe, Asia, and Latin America. TI is a global leading semiconductor manufacturer and has an important influence on multiple fields such as computers, communications, industrial control, and healthcare.
The history of Texas Instruments can be traced back to 1930 when inventor and engineer James Korklewski established Geophysical Service Incorporation to create a sales company for electronic equipment. In 1941, TI was restructured into an independent company and began to engage in scientific and technological research and development and semiconductor production. TI first introduced transistors in the 1950s. In the 1960s, the company began to engage in the integrated circuit industry and produced the world's first single-chip microcomputer in 1971, which greatly changed the development model of the computer industry.
Texas Instruments products include analog integrated circuits, digital signal processors, single-chip microcontrollers, power management devices, chip solutions, and radio frequency controllers. These electrical components are sold to the aerospace, defense, industrial, personal electronics, and communications markets. They cover portable audio devices, high-definition televisions, car navigation, mobile phones, automotive signal processing, industrial control equipment, and security protection.
Texas Instruments' globalization strategy relies on an understanding of cross-cultural, language, and technology. In the past few decades, TI has expanded its business globally. It is very popular in the Asian market. The company has opened offices and factories in China, Southeast Asia, and India, aiming to expand its market share and improve competitiveness.
