Logic translators, level shifters, such as the 74AVC20T245DGGRG4, are specialized integrated circuits (ICs) designed to bridge between digital logic levels. The main purpose of logic translators is to allow two logic circuits to be plugged into a single circuit, even if their power supply voltages and voltage levels are different. In addition, these components can be used for applications such as crossing between different bus protocols and bus arbitration.

The 74AVC20T245DGGRG4 is a dual-channel integrated universal logic level translator specifically designed to operate between 2.5 V and 3.3 V logic families. It provides full bidirectional voltage level translation between any two logic families without the need for external components or reference voltages. It features low propagation delay of 5 ns (typical) and Schmitt-trigger inputs with active-low enable. The 74AVC20T245DGGRG4 is available in space-saving 0.3 inch width 8-pin dual in-line packages (DIP), making it suitable for use in a variety of applications.

The working principle of 74AVC20T245DGGRG4 can be explained with a simple analogy. Imagine two systems, A and B, each with a different logic level threshold in the signal range. Suppose the signal voltage level that is considered ‘logic one’ for system A is larger than the ‘logic one’ signal voltage level for system B. In this case, the 74AVC20T245DGGRG4 IC will convert the higher logic levels of system A to the lower logic levels of system B, while still maintaining the signal fidelity. This is done by taking the voltage level of the input signal, comparing it to the thresholds of both systems and generating an output signal with the correct voltage level.

The 74AVC20T245DGGRG4 can serve many different applications, with the most common ones being in electrical and electronic test equipment, automotive and industrial automation. Also, since the 74AVC20T245DGGRG4 supports operation between different logic families, the IC is used in many applications where logic level compatibility is critical such as in datacom, SAN, and LAN applications. Additionally, the 74AVC20T245DGGRG4 is used in applications where power efficiency and space savings are of utmost importance such as portable devices, smartphones and tablets.

In summary, the 74AVC20T245DGGRG4 is a IC designed specifically for use as a logic translator and level shifter. It allows two circuits with different logic levels to interact without needing external components or reference voltages. This IC is especially useful for applications such as data communications, automotive and industrial automation, as well as power efficiency and space savings.
