Texas Instruments SN74AXC Level Transmitters

27.10.2018

Texas Instruments has released new AXC series level converters. As an example, one of the representatives of the series - SN74AXCH8T245 - is an 8-bit level converter between low-voltage components operating from 0,7 V - 0,9 V voltages and components operating from standard 1,8 V - 3,3 V power rails.

The converter has two control outputs for setting the transmission direction DIR1 and DIR2, which control the transmission directions of the groups of outputs 1-4 and 5-8, which, together with the output driver enable pin (OE), allows you to flexibly implement synchronous or asynchronous information transfer.

Features of converters of the AXC family:

wide range of supply voltages Vcc: 0,65...3,3 V (for each channel);
compatibility with devices with partial shutdown of blocks;
automatic shutdown of outputs when the power is turned off;
power-on transient suppression;
supply voltage level control;
50% less power loss (compared to other families);
low cost.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

There is a direct link between hunger and pain 29.03.2018

An international group of scientists conducted a study, the results of which showed that the elimination of pain is directly related to hunger. Note that this result extends even to chronic syndromes.

In order to prove or disprove the connection between pain and hunger, experts conducted a study on laboratory mice. Before the experiment, mice had one of the paws damaged. For some time, the subjects were not given food, which led to the fact that the nerve receptors responsible for pain began to send signals to the brain. This experiment led the mice to stop licking their injured paws as they stopped feeling pain.

Note that this experiment has not yet been carried out on humans. However, experts are working in this direction, because if fasting really makes it possible not to feel pain, then this study will be a discovery in both medicine and science.
