PI4IOE5V9554 8-bit IO Expander Diodes Incorporated PI4IOE5V9554 8-bit IO Expander is a 16-pin CMOS device that provides 8-bit of General Purpose parallel Input/Output (GPIO) expansion. This expander incorporates an 8-bit configuration register (input or output selection) and an 8-bit input port register. The PI4IOE5V9554 expander also includes an 8-bit output port register and an 8-bit polarity inversion register (active HIGH or active LOW operation). This expander features high drive capability, 5V I/O tolerance, low supply current, individual I/O configuration, 400kHz clock frequency, and small packaging. The PI4IOE5V9554 expander offers a noise filter on SCL/SDA inputs, no glitch on power-up, and internal power-on reset. This expander provides a simple solution when additional I/O is needed for ACPI power switches, sensors, pushbuttons, LEDs, and fans.
