The PCF8575DWR from Texas Instruments is a 16-bit quasi-bidirectional I/O expander that communicates via the I2C interface. This device is suitable for applications requiring additional I/O pins, offering 16 general-purpose inputs/outputs that can be controlled by a microcontroller. It operates within a voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 400kHz.
The expander features an interrupt output pin, which can be configured as open-drain, to signal changes in I/O states. The latched outputs provide high-current drive capability, allowing for direct driving of LEDs. The device is available in a 24-SOIC package, designed for surface mounting.
With its low standby current consumption and compatibility with most microcontrollers, the PCF8575DWR is a versatile solution for expanding I/O capabilities in embedded systems. The address can be set using three hardware address pins, enabling up to eight devices on the same I2C bus.
