The PCA9534BS3,118 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 I2C-bus I/O expansion with features like 5V I/O tolerance, low supply current, individual I/O configuration, and a 400 kHz clock frequency.
This IO 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 inputs or outputs by writing to the I/O configuration bits. The device features an open-drain interrupt output that activates when any input state differs from its corresponding input port register state.
Key electrical specifications include an operating supply voltage range of 2.3V to 5.5V, 5V tolerant I/Os, and a maximum clock frequency of 400 kHz. The device supports I2C and SMBus interfaces. It is offered in a 16-HVQFN (3x3) package, suitable for surface mounting.
The PCA9534BS3,118 operates within a temperature range of -40°C to 85°C. It includes features like a power-on reset (POR) and ESD protection exceeding 2000V HBM. This component is ideal for applications requiring additional I/O for ACPI power switches, sensors, push buttons, LEDs, and fans.
