Logic translators and level shifters have been developed over the past several years in order to effectively increase digital signal transmission levels and to extend input and output range levels. As technology continues to grow and evolve, there are new products that are introduced that offer advantages over the standard parts that were used in the past. One such product is the MC10ELT21DTG, used for efficient translation of logic signals between two different voltage levels. This article will discuss this product, its application fields, and its working principle.

The MC10ELT21DTG is a low-cost, high-speed, low-power non-inverting logic level translator for pseudo open-collector and open-drain designs. It is used for efficient translation of logic signals between interfaces having different logic levels that occur due to different voltage levels between communicating circuits. The device supports voltage levels of 1.2 and 3.3 V and provides a translation voltage of 0.9 V to 7.5 V in a typical configuration. Its low power requirement makes it well-suited for battery-powered applications, such as portable electronics.

In a typical application, the VIE pin is connected to the most positive supply voltage present, VDD, and the VIC pin is connected to the most negative supply voltage present, VSS. The output drivers then receive their input signals from the interface and terminate their outputs to the VDD and GND reference voltages.

The MC10ELT21DTG device has the following application fields: it is used in memory cards, personal digital assistant (PDA) and mobile communications applications, netbooks, and other portable products. It is also used in high-speed serial interfaces, such as SVMi, USB, and HDMI; in peripheral interface controllers, such as Bluetooth, SDIO and SPI; in power management circuits, such as switching converters; and in analog-to-digital and digital-to-analog converters.

The working principle of the MC10ELT21DTG device is based on voltage-divided circuits. Its internal circuitry is divided into several stages and it consists of a pair of voltage dividers and two comparators. The first stage consists of the input voltage dividers, which consist of two resistors. These dividers divide the input supply voltage into two smaller levels, which are then passed to the two comparators. The output of the comparators is then fed to the output buffers.

The MC10ELT21DTG logic translator also has a feature which allows for the system voltage to be monitored and controlled. This feature is referred to as the Adaptive Voltage Scaling (AVS). The AVS allows the system to dynamically adjust to supply voltage variations by scaling the internal voltage level. This allows for the system voltage to remain constant, even when the input supply voltage changes. This helps to reduce power consumption, as the device does not need to continuously adjust its output levels.

In conclusion, the MC10ELT21DTG is an innovative product from Texas Instruments and it offers superior performance with minimal power consumption. It can be used in a wide variety of applications, such as in memory cards, digital interfaces, and analog-to-digital and digital-to-analog conversions. Its working principle is based on voltage-divided circuits and its Adaptive Voltage Scaling feature allows it to remain stable in varying input voltage conditions. This product can be an excellent choice for designers looking to increase digital signal transmission levels and extend input and output range levels.
