MAX9376EUB+ is an integrated logic isolator and level-shifter IC with a variety of efficient application fields, as well as its advanced working principle that allows it to support various transmission and voltage levels. This article will discuss both of these aspects in greater detail.

Application Fields

MAX9376EUB+ is ideal for applications that require logic-level interfacing between devices operating at different logic levels, such as 3.3V and 5V, or between devices operating at different data rates, such as slow and fast clocks. As an example, this device can be used in optical transceivers, as well as in providing a reliable, low-power link between a host system and an external device, as a single IC. This type of application requires it to provide both level-shifting and logic isolation, to ensure signal integrity and to reduce signal degradation.

MAX9376EUB+ can also be used in end-to-end links between two devices, such as between a microcontroller and a transmitter. This type of application requires the device to isolate and protect the transmitter from the microcontroller’s signal, while simultaneously converting the digital signals from the microcontroller to the appropriate voltage levels for the transmitter. It is especially useful for situations in which the microcontroller and transmitter are operating at significantly different data rates, in order to ensure signal integrity.

Working Principle

MAX9376EUB+ has an input-to-output delay of less than 4ns, allowing it to provide very fast signal propagation speeds from the microcontroller to the transmitter. It also has an output-to-input delay of less than 14ns, which allows it to process signals quickly and efficiently.

MAX9376EUB+ provides both galvanic and electrical isolation between the microcontroller and the transmitter, isolating the transmitter from power supply noise, ground loop interference, and other electrical disturbances that could potentially cause signal degradation and loss. This device also provides ESD protection to both the microcontroller and the transmitter, ensuring a safe and reliable link between the two devices.

MAX9376EUB+ has the ability to detect the logic level of the input signal, and automatically convert it to the appropriate output logic level and data rate. This feature allows it to support a wide range of input logic levels, from 0.7V to 6.0V for TTL, as well as from 1.7V to 6.0V for CMOS. This device is also capable of supporting a wide range of data rates, from 6ns to 125MHz, allowing it to support both slow and fast clock speeds.

MAX9376EUB+ also has an integrated voltage regulator, providing high levels of ESD protection in both directions. The device also has an adjustable overvoltage detection circuit, allowing it to detect overvoltage conditions and protect the transmitter from electrical disturbances. This device also has a wide input and output common-mode range, allowing it to support different input and output common-mode voltages.

Conclusion

MAX9376EUB+ is a versatile logic isolator and level-shifter IC, providing a variety of efficient application fields and advanced working principle. It is capable of supporting a wide range of logic levels, data rates, and other electrical conditions, making it ideal for a variety of applications. With its integrated voltage regulator, adjustable overvoltage protection, wide common-mode range, and fast signal propagation speeds, MAX9376EUB+ is an excellent choice for applications requiring both level-shifting and logic isolation.
