The MAX13055EEWG+T is a Logic-Translators, Level Shifters integrated circuits, which is optimized for wide range of applications and provide a low-cost solution for translating ‘3.3V’ digital signals to ‘5V’ or ‘2.5V’ outputs. The core of the device consists of a voltage-controlled, variable-delay line,which are compatible with TTL and CMOS logic levels. The integration of this device features make it ideal for many designs involving logic levels translation, and provides faster switching speeds, higher noise immunity and reduced power consumption.

The application of this device is mainly used in logic-level converter and logic-level translator, such as voltage implementation of logic level translation for FPGA I/O interface to transceivers, switching and other mixed-signal products. Besides, it also can match the termination resistance for the lower voltage I/O interface to signals with higher voltage with the out-of-spec output voltage margin. In addtion, the device can be used to drive low voltage loads from higher voltage supply, such as MCUs and memories.

The working principle of MAX13055EEWG+T is that the voltage-controlled delay line provides fast propagation time and excellent noise margin. It will constantly monitor the input level, and consequently select appropriate delay to match the output voltage level. This devicehas two Delay Setup options, one of them can be programmed as internal controlled delay, and the other one is a externally controlled delay. Both of them can provide decrease the propagation delay time to meet other system design criteria.

The ‘3.3V’ digital signals translated by this device is coupled to internal regulator which then feeds the high speed, low latency delay line, along with CMOS or TTL high speed buffers. The delay line and the voltage monitor can be one-to-one or one-to-many parallel connections and the feedback from output will be used to adjust the delay. The delay line also can be used as a series glue stage tplrive the next logic block or bus structure.

The output of this device is a logic-level, which can be connected to a source-synchronous FPGA I/O receiver for broadcast applications or to bidirectional SRAM. The switching speed of the outputs is much faster than a traditional voltage-level translator, providing high-speed and low-voltage differential signaling compliance. The low-voltage interface of MAX13055EEWG+T is capable of driving a large number of low-voltage devices,-be it a microcontroller, memory controller, or other digital logic devices.

The MAX13055EEWG+T is a versatile device that can be used in a wide range of applications. In a typical application, it can be used to convert ‘3.3V’ TTL or CMOS digital signals to ‘5V’ or ‘2.5V’ logic levels, as well as to provide a low-cost solution for logic-level translation. The device also offers excellent noise immunity, providing a better noise margin for design engineers. Furthermore, the device can be used to drive low-voltage loads from higher voltage supplies.
