The FXMA2104UMX is a logic-translator, level shifter integrated circuit. It is commonly used to translate signal levels between compatible logic families in industry applications. The integrated circuit utilizes hot electrostatic discharge protection, as it closes circuits between two different logic circuits within an application.

The FXMA2104UMX functions with FET transmission gates that allow signal switching and level shifting between TTL, 5V CMOS and 3.3V CMOS digital logic families. The integrated circuit is specifically designed for Half-Duplex RS-485 and RS-422 bus systems. The transmission gates are compatible with CMOS inputs, allowing the IC to function within logic families with digital input voltages as low as 0.8 V or 3.3 V.

The FXMA2104UMX provides logic level amplification between 2 different logic families, allowing signal channels to pass into R-terminals of CMOS devices. Moreover, the integrated circuit simplifies bridge designs, as end-users do not need to attach external components that are typically used in the level shifting of signal levels in bridge circuits.

The FXMA2104UMX provides features 3 kV Human Body Model (HBM) ESD protection. This protection circuitry is extremely important, as it prevents damage to the signal channels within the circuit. Excessive voltage flows of more than 3 kV can be lethal to integrated circuits, making the ESD protection a necessary feature.

The FXMA2104UMX provides several features that make it suitable for a wide range of industrial applications. The number of channels is selectable for 1 to 8 channels and the total power consumption is low to minimize heat development. The integrated circuit provides overcurrent protection of 500 mA in order to protect the RS-485 and RS-422 based systems from overcurrent loading. The extended operating temperature range is from -40℃ to 85℃ for reliable operation in harsh environments.

In general, the is capable of generic level shifting and logic families conversions as long as the input/output voltage requirements are respected. With its multiple high-speed, reliable, and low-power features, the FXMA2104UMX integrated circuit can help to provide cost efficiencies in a wide range of data-communications systems.
