EVALUATION KIT AVAILABLE  
MAX31910  
Ultra-Low Power Industrial, Octal, Digital Input  
Translator/Serializer  
General Description  
Benefits and Features  
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. It provides the front-end interface  
circuit of a programmable logic controller (PLC) digital  
input module.  
Ultra-Low Power and Heat Dissipation  
• Low Quiescent Current (1.4mA typ)  
• Highly Accurate and Stable Input Current Limiters,  
Adjustable from 0.5mA to 6mA  
• Special (Patent-Pending) Ultra-Low-Power Mode  
with Switched Current Limiters  
High Integration Reduces BOM Count, Board  
Size, and System Cost  
The device features integrated current limiting, lowpass  
filtering, and channel serialization. Input current limit-  
ing 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.  
• 8 High-Voltage Input Channels (36V max)  
• On-Chip 8-1 Serialization with SPI Interface  
• On-Chip 5V Regulator  
• On-Chip Overtemperature Indicator  
• On-Chip Field Supply Voltage Monitor  
• Integrated Debounce Filters, Selectable from 0 to 3ms  
Robust Features and Performance for Industrial  
Environments  
• Multibit CRC Code Generation and Transmission for  
Error Detection and More Reliable Data Transmission  
• High ESD Immunity on All Field Input Pins  
Accepts Industry Standard Input Types  
• Configurable for IEC 61131-2 Input Types 1, 2, and 3  
Flexible Power Supply Capability Enables Usage  
in 5V, 12V, 24V, and Higher Voltage Systems  
• Wide Operating Field Supply Range of 7V to 36V  
• Can Be Powered From the Logic-Side Using a 5V  
Supply  
Selectable on-chip lowpass filters allow flexible debouncing  
and filtering of sensor outputs based on the application.  
On-chip serialization allows a drastic reduction in the  
number of optocouplers used for isolation. The device  
serializer is stackable so that any number of input channels  
can be serialized and output through only one SPI-  
compatible port. This reduces the number of optocouplers  
needed to only three, regardless of the number of input  
channels.  
For enhanced robustness with respect to high-frequency  
noise and fast electrical transients, a multibit CRC code  
is generated and transmitted through the SPI port for  
each 8 bits of data. The on-chip 5V voltage regulator can  
be used to power external optocouplers, digital isolators,  
or other external 5V circuitry.  
Applications  
Digital Input Modules for PLCs  
Industrial, Building, and Process Automation  
Motor Control  
For low-cost applications, Maxim Integrated offers a  
pin-compatible version of this device, the MAX31911.  
The MAX31911 does not include the patent-pending  
current clamp-switching circuitry that is included with the  
MAX31910.  
The MAX31912 and MAX31913 versions includes energy-  
less LED drivers while maintaining pin compatibility.
