The MAX3391EEBC+T is a universal level-shifter, with voltage range from 5.5V to 8.0V, that buffers up four different voltage signals and points. Different type of logic families such as TTL, HCMOS, and low-voltage MOS compatible signals can be used, so the user has the ability to design versatile mixed-voltage systems. It is suitable for applications that require a data rate ranging up to 40MHz. This article will discuss the application field and working principle of the MAX3391EEBC+T.

Application Field

The MAX3391EEBC+T translates signals between two different logic levels, allowing expansion of the logic family of an existing system. It is designed for use with different logic families, such as CMOS, TTL, and, MOS compatible signals. The bi-directional I/O pins can be configured for either two way or four way translation depending on the application. The MAX3391EEBC+T can also be used to shift voltage levels from one to the other. This is accomplished by using the translator\'s internal impedance matching configuration. This allows for different combinations of voltage levels, making it an ideal solution for products that require Mixed-signal Networks. The MAX3391EEBC+T is also used in applications where current level translation is required as it has an integrated current driver.

Working Principle

The MAX3391EEBC+T employs a scheme to achieve level-shifting and buffering. Its output is enabled by the logic high signal detected on the enable pins EN1 and EN2. When EN1 and EN2 are low the translator is in high-impedance state and the output is disabled. The logic levels are determined by the reference voltage VREF. The output when enabled is equal to VREF-VS which can be varied by setting the voltage between VREF and VS. This output level is then translated to the opposite signal level via the internal impedance matching of the translator. The current is also limited to 4mA. This buffering and level shifting from one signal to another is the basis of the working principle of the MAX3391EEBC+T.

Conclusion

The MAX3391EEBC+T is a versatile level shifter device designed to translate logic levels between different logic families such as TTL, HCMOS, and low-voltage MOS compatible signals. It is used in applications where the translation of one logic level to another is needed and also in applications where current level translation is required. Th MAX3391EEBC+T can be used to shift voltage levels from one to the other using an integrated current driver and internal impedance matching. This makes the MAX3391EEBC+T an ideal solution for products that require Mixed-signal Networks.
