Logic-Translators, Level Shifters, and Decoders are electronic components used to convert digital logic levels. The NB4L16MMNR2G is a logic-translator and level-shifter integrated circuit and will be discussed in this article, focusing on its application field and working principle.

The NB4L16MMNR2G is a logic level translator, which is a device which acts as an interface between two different voltage circuits. It is a monolithic device that provides bidirectional level translation. It allows interfacing of logic signals of one voltage to logic signals of another voltage, while preserving the signals\' integrity. This makes it very useful in many applications, such as interfacing between low voltage CMOS circuits and high voltage ECL circuits, or between low and high voltage thresholds of the same technology.

The NB4L16MMNR2G is a bite-level interface and is used to bridge logic between ASICs, FPGAs and I/O devices. It is designed to accommodate a variety of logic voltages, including 3.3V, 2.5V, 1.2V, 1.0V, and 0.8V, as well as bidirectional level shifting. It is an ideal choice for interfacing between two unlike busses or two unlike logic families such as LVC, HDLC, HSTL,lvH, and LVDS.

The NB4L16MMNR2G is a 16-bit level shifter providing low input thresholds, ensuring that logic low levels are compatible with both low- and high-voltage logic standards. The input logic thresholds are maintained at 1.2V and the output logic thresholds are maintained at 2.2V, providing a bridge between logic that is either higher or lower than the input logic threshold.

The working principle of the NB4L16MMNR2G is simple. It is a two stage device consisting of an output buffer and a control and level shift stage. The input stage detects the logic levels of the input signals and passes them through to the output buffer. The control and level shift stage in turn translates the logic levels to either the low or high side of the output buffer, depending on the direction of data transfer. This allows the NB4L16MMNR2G to achieve bidirectional level shifting.

In conclusion, the NB4L16MMNR2G is a useful component for interfacing between two different voltage circuits, allowing a low input voltage to be translated into a higher output voltage, or alternatively allowing a higher input voltage to be translated into a lower output voltage. Main applications of the NB4L16MMNR2G include logic level translation between dissimilar busses and logic families, as well as interfacing between low and high voltage standards. Its working principle is relatively straightforward, relying on an input stage to detect the input logic levels and pass them to the output buffer, and a control and level shift stage to translate the logic levels to either the low or high side of the output buffer.
