GPIO Expanders


NXP Semiconductors' industry-leading GPIO expanders provide 4, 8, 16, 24, or 40 general purpose I/O pins for the CPU via the I2C bus to help designers reduce board space and complexity and simplify software development time for lower overall system cost.

  • Robust performance from the I2C inventors: rock solid performance and specification conformance eliminates miscommunication and system hang up issues 
  • Broadest portfolio: complete line of industry-standard and special-function devices simplifies procurement and minimizes qualification costs with a single supplier
  • Differentiated devices: help the users' systems stand out in the market
    • Lowest I2C bus power supply voltage down to 0.8 V eliminates level translation
    • Smallest, thinnest packages available save space: 2 mm x 2 mm x 0.35 mm 24-pin land grid array
    • Agile I/O GPIO includes features to eliminate external components like pull up resistors, open drain outputs, output drive control, and input latches to permit faster software development and more robust firmware performance
