MAX31913 Overview
Key Specifications
Package: TSSOP
Mount Type: Surface Mount
Pins: 28
Max Voltage (typical range): 36 V
Description
The MAX31913 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.
Key Features
- integrated current limiting, lowpass filtering, and channel serialization
- Selectable onchip 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 SPIcompatible port
- This reduces the number of optocouplers needed to only three, regardless of the number of input channels
