The MAX3023EBC+TG47 is a precision, low-power CMOS logic-level translator with automatic flow control. It is one of the most versatile and cost-effective level shifters available on the market today. It has been designed to provide logic-level compatibility between devices operating at different logic thresholds, and is well suited for both industrial and low-cost consumer applications.

The MAX3023EBC+TG47 is suitable for a wide range of applications, including communications, gaming, medical instrumentation, and embedded systems. It is especially well-suited for applications requiring low active power dissipation and fast switching speeds. It can be used to convert TTL/CMOS to/from USB, I2C, Ethernet, RS-232, etc.

Working Principle

The MAX3023EBC+TG47 works using a programmable threshold voltage generator. This voltage generator utilizes the input and output logic levels of the application, which can be selected from 2.5V, 3.3V, 4.5V, 5V and 8V. The threshold voltage generator is connected between the input and output signals, and the output is then converted to the input logic level. The output voltage is automatically adjusted to compensate for the difference in logic levels between the two signals.

The MAX3023EBC+TG47 operates in one of two modes. The first mode is the "Bio-gate" method, which adjusts the logic level of the output signal so that it is within a predetermined range of the input signal. This allows the logic-level translator to remain in a static logic state until a change in input logic level occurs. The second mode is the "Rail-to-Rail" method, which adjusts the output logic level so that it is always equal to or lower than the input logic level. This ensures that the circuit remains in the active state but will not exceed the input voltage.

The MAX3023EBC+TG47 also has an automatic flow control feature, which ensures that the logic-level translation is always within a predetermined range. This is especially beneficial when interfacing devices with logic levels that may be too far apart to guarantee accuracy using the first two methods.

Conclusion

The MAX3023EBC+TG47 is a versatile and cost-effective logic-level translator. It is suitable for a wide range of applications, including communications, gaming, medical instrumentation, and embedded systems. The MAX3023EBC+TG47 operates using two methods, Bio-gate and Rail-to-Rail, which ensure that the output logic level is always within a predetermined range of the input logic level. The MAX3023EBC+TG47 also has an automatic flow control feature, which ensures further accuracy in logic-level translation.
