Alternative Part Number

  • PCF8574T --: Widely available I2C 8-bit I/O expander in SOIC package, functionally similar to the IL223AT interface expander and easy to source.
  • MCP23008-E/SO --: I2C 8-bit I/O expander with comparable pin count and supply range, suitable drop-in functional replacement in most designs.
  • TCA9554APWR --: Low-voltage I2C I/O expander with similar functionality and package options, good second-source alternative when the original is unavailable.
