PCA9536 4-bit I²C-bus And SMBus I/O Port

The PCA9536 is an 8-pin CMOS device that provides 4 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. I/O expanders provide a simple solution when additional I/O is needed for ACPI Power Switches Sensors push buttons, LEDs fans, etc. The PCA9536 consists of a 4-bit Configuration Register (input or output selection), 4-bit Input Port Register 4-bit Output Port Register and a 4-bit Polarity Inversion Register (active HIGH or active LOW operation). The system master CAN enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding Input Port or Output Port Register The polarity of the read Register CAN be inverted with the Polarity Inversion Register All Registers CAN be read by the system master. The power-on reset sets the Registers to their default values and initializes the device state machine. The I2C-bus address is fixed and allows only one device on the same I2C-bus SMBus
