Logic translators and level shifters are commonly used in modern electronic system designs to convert digital signals, such as those from a microprocessor, from one logic level, or level of logic, to another. In particular, the MC100EPT20DR2 is to be used to Perform Double Data-Rate Level Translators between the Low-Voltage Current-Steering Logic (LVCMOS) 3.3V level and the more widely-used ECL levels of 0.8V and –1.5V.

Application Field of the MC100EPT20DR2

The MC100EPT20DR2 is widely-used in systems with complex exchanges of digital data between two different logic families. A common place to find this device is in networks where ECL standard signal levels are to be transitioned to compatible LVCMOS signals, such as in various types of communication and signal processing hardware. In addition, its wide differential signal compatibility and transmission distance make it a very useful choice for system designs using long signal traces subject to signal noise and crosstalk, both of which can be minimized with the MC100EPT20DR2’s internal signal buffering capabilities.

The MC100EPT20DR2 is part of ON Semiconductor’s wide selection of logic translators and level shifters, and it offers a number of features that make it a great choice when data needs to be converted between different logic families, such as ECL, LVCMOS, and CMOS logic signals. In particular, the MC100EPT20DR2 provides a low-power solution due to its current-steering logic and differential output stage, and it offers a wide range of signal levels, from 0.8V to 3.3V, for all the different levels of logic typically found in today’s systems. It also has a propagation delay of 8 ns, ensuring fast signal conversion, and an output pulse width of 10 ns, which helps to minimize any signal distortion that could occur.

Working Principle of the MC100EPT20DR2

The MC100EPT20DR2 employs a current-steering logic (CSL), also referred to as current mode logic, to provide its logic-level to logic-level translation. As the name implies, CSL is a logic-level conversion technique that works by changing or “steering” the amount of current flowing through the gate of a transistor to create different digital logic levels. It is similar in concept to CMOS (complementary metal-oxide semiconductor) logic which also uses transistors to switch between digital logic states. In the case of the MC100EPT20DR2, it is used in combination with an internal differential output stage which helps to reduce signal noise, crosstalk, and potential resistor or capacitor mismatches that can degrade signal transmission between two logic levels.

To further improve signal integrity, the MC100EPT20DR2 also employs an internal power-down feature which can be used to disable the output stage and turn off the device. This helps to reduce the power consumption of the device, allowing it to be used in more power-sensitive applications. Additionally, it also has an output control pin which can be used to force the output stage to a logic state of either high or low, allowing the device to be used as a high-current buffer or in other applications where it is needed.

In summary, the MC100EPT20DR2 is a highly versatile logic translator and level shifter that provides a low-power solution for converting between different digital logic levels. Its features make it ideal for use in long signal pathways subject to signal noise and crosstalk, and its low power consumption makes it suitable for systems which may be designed with strict power requirements. Additionally, its differential output stage and output control pin provide added versatility, making it a great choice for any type of logic level conversion design.
