MC100LVEL01DT application field and working principle

MC100LVEL01DT is a very popular high-speed, low-voltage, voltage-level-translator from ON Semiconductor. It is part of the logic gates and inverters family and it can be used for various applications. The MC100LVEL01DT is a multi-functional, configurable level translator that can operate at a power supply voltage range from 1.8V to 5.5V. This range makes it suitable for interfacing devices that are powered by different voltages.

The MC100LVEL01DT is designed for use in applications that require multiple voltage levels, such as today\'s embedded systems, automotive and communications systems. It provides a low-voltage, high-speed operation, allowing it to be used in high-speed communication systems such as Ethernet, USB and ATM. The device is also compatible with most popular logic families and has excellent noise immunity, making it extremely versatile.

The working principle of the MC100LVEL01DT level translator is relatively simple. The device contains two separate input and output ports. The input port has two different voltage levels that are detected by the internal comparator. When the input voltage is at a higher voltage than the output voltage, the device stores the difference as charge on an internal capacitor. When the output voltage falls below the input voltage, the device discharges the stored charge, effectively translating the voltage level from one voltage level to the other.

The device also contains two internal logic levels for further configurability. The positive logic level, referred to as the “VT”, will force the output port to a logical “high” if the input port is above the VT threshold, and will force the output port to logical “low” if the input voltage is below the VT threshold. The negative logic level, referred to as the “VTN”, works in reverse, resulting in the output port logic being “high” if the input voltage is below the VTN threshold, and “low” if the input voltage is above the VTN threshold. These two internal logic levels provide additional capability to the level translator, making it suitable for applications that require multiple voltage levels.

In short, the MC100LVEL01DT level translator is an ideal solution for interfacing devices powered by different voltages, providing low-voltage, high-speed operation, excellent noise immunity, and configurable logic levels. It is an ideal solution for embedded systems, automotive and communication systems that require a reliable level translator.
