The PCA9534 is a 16-pin CMOS device that provide 8 bits of General Purpose parallel
Input/Output (GPIO) expansion for I2C-bus/SMBus applications and was developed to
enhance the NXP Semiconductors 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, etc.
