The PCA9535DWR is a 16-bit general-purpose I/O (GPIO) expander designed by Texas Instruments. It communicates via the I2C and SMBus interfaces, supporting clock frequencies up to 400 kHz. This device is suitable for applications requiring additional I/O pins, operating within a voltage range of 2.3V to 5.5V.
Key features include an open-drain active-low interrupt output, configuration registers, and latched outputs with high-current drive capability. The PCA9535DWR is available in a 24-SOIC package, designed for surface mounting. It operates across a temperature range of -40°C to 85°C.
With its 5-V tolerant I/O ports and compatibility with most microcontrollers, the PCA9535DWR offers flexibility in system design. It supports addressing by three hardware address pins, allowing up to eight devices on the same bus. The low standby-current consumption of 1 µA makes it an energy-efficient choice for various embedded systems.
