Interface

I/O ExpanderI2CGPIO

The PI4IOE5V9554LEX is an 8-bit I2C/SMBus I/O expander designed for adding GPIOs to systems via a 2-wire serial interface.

Best for

  • Adding GPIOs to microcontrollers with limited pins
  • ACPI power switches
  • Sensor interfaces

Avoid if

  • High-speed data transfer is required
  • Very low-power battery applications where 500uA standby current is excessive

Check before use

  • I2C address conflicts
  • Interrupt pin logic levels
