The PCA9538PW,112 from NXP Semiconductors is a versatile 8-bit General Purpose Input/Output (GPIO) expander designed for I2C-bus and SMBus applications. This CMOS device provides a simple solution for systems requiring additional I/O for components like sensors, push-buttons, and LEDs.
Key features include an operating supply voltage range of 2.3 V to 5.5 V and 5 V tolerant I/Os. It supports a clock frequency of up to 400 kHz and includes an active LOW interrupt output and an active LOW reset input. The device consists of configuration, input port, output port, and polarity inversion registers, all readable by the system master.
This I/O expander is supplied in a 16-TSSOP package, suitable for surface mounting. It operates within a temperature range of -40°C to 85°C, making it adaptable for various environmental conditions. The PCA9538PW,112 is designed for efficient power management, offering low standby current.
Applications for the PCA9538PW,112 include expanding I/O capabilities in embedded systems, ACPI power switches, and various sensor interfaces where additional digital control is needed.
