Key Features

  • SPI Serial Interface: Allows for easy communication with microcontrollers.
  • 16 Input-Only I/O Pins: Monitors the status of up to 16 switch inputs.
  • Interrupt Output: Generates an interrupt when the input port status changes, with the ability to mask selected inputs.
  • 18 V Input Tolerance: Each input port has 18 V breakdown ESD protection, allowing it to tolerate various voltage conditions.
  • Low Power Consumption: Operates with a supply current of typically 2.5 μA at VDD = 5.5 V.
  • Flexible Interrupt Handling: The interrupt output is enabled/disabled via the INT_EN pin, and selected inputs can be masked to not generate interrupts.

Applications

  • Microcontroller-Based Systems: Expands the I/O capabilities of microcontrollers in various applications.
  • Industrial Automation and Control: Suitable for monitoring switch inputs in industrial automation systems.
  • Consumer Electronics: Used in consumer electronics for input monitoring and I/O expansion.
