Application Scenarios & Design Considerations

Worlds Lowest Voltage Level

Alternative Part Number

  • PCA9555PW --: 16-bit I2C GPIO expander with interrupt output, widely available and functionally similar to the SX1509 for general GPIO expansion applications.
  • TCA9555PWR --: Pin-compatible 16-bit I2C/SMBus I/O expander with interrupt, low-power CMOS, direct functional substitute in most designs.
  • MAX7311AUG+ --: 16-bit I2C port expander with interrupt and hot-insertion support, suitable alternative when keypad/LED features of SX1509 are not required.
