The PCA9534 is a16-pin CMOS device that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C/SMBus applications and was developed to enhance the Philips family of I2C I/O expanders.
The improvements include higher drive capability, 5V 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, pushbuttons, LEDs, fans, etc.
