The PCA9534PW,118 from NXP Semiconductors is a 16-pin CMOS device providing 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications. It is designed to enhance existing I2C-bus I/O expander families with features like higher drive capability, 5V I/O tolerance, lower supply current, individual I/O configuration, and a 400kHz clock frequency.
This I/O expander includes an 8-bit Configuration register, an 8-bit Input register, an 8-bit Output register, and an 8-bit Polarity Inversion register. The system master can configure the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is stored in the corresponding Input or Output register, and the polarity of the Input Port register can be inverted.
The PCA9534PW,118 operates with a supply voltage range of 2.3V to 5.5V and features 5V tolerant I/Os. It has an active LOW interrupt output that is activated when any input state differs from its corresponding input port register state, indicating a change to the system master. The device is offered in a 16-TSSOP package and supports surface mount installation.
Key features include an 8-bit I2C-bus GPIO, a low standby current, noise filtering on SCL/SDA inputs, and an internal power-on reset. The device is suitable for applications requiring additional I/O for ACPI power switches, sensors, push buttons, LEDs, and fans.
