MAX31910 - Digital Input Translator/Serializer

The MAX31910 industrial interface serializer translates, conditions, and serializes the 24V digital output of sensors and switches used in industrial, process, and building automation to 5V CMOS-compatible signals required by microcontrollers.

• integrated current limiting, lowpass filtering, and channel serialization. Input current limiting allows a significant reduction in power consumed from the field voltage supply as compared to traditional discrete resistor-divider implementations. In addition, to achieve the lowest in-class power dissipation, the device uses patent-pending circuit techniques to achieve further reduction of power beyond what is possible by input current limiting alone. Selectable on-chip lowpass filters allow flex.
