PCF8575PWR Description

Short technical summary and product information.

The Texas Instruments PCF8575PWR is a versatile 16-bit I/O expander that facilitates remote I/O expansion for microcontrollers via the I2C interface. It supports a wide operating voltage range of 2.5V to 5.5V, making it suitable for various system designs.

 

This device offers 16 quasi-bidirectional input/output pins, including latched outputs with high-current drive capability, ideal for directly driving LEDs. It operates at a fast I2C bus frequency of up to 400kHz and features an open-drain interrupt output. The PCF8575PWR is designed for surface mount applications and comes in a 24-TSSOP package.

 

With a low standby current consumption and compatibility with most microcontrollers, the PCF8575PWR is a practical choice for expanding digital I/O capabilities in embedded systems. Its address can be set using three hardware address pins, allowing up to eight devices on the same bus.
