Datasheet Diodes PI4IOE5V9554A
8-BITS Io Expander
2 8-bit I C-Bus and SMBus I/O Port with Interrupt
The PI4IOE5V9554 are 16-pin CMOS devices that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and were developed to enhance the Diodes family of I2C-bus I/O expanders.
The improvements include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, 400 kHz clock frequency, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, and so on.
