Description and Introduction

Remote 16-Bit I2C and SMBus I/O Expander with Interrupt Output 24-TSSOP -40 to 85 The **PCF8575PW** is a versatile **I/O expander** integrated circuit designed to enhance the input/output capabilities of microcontrollers and other digital systems. Manufactured in a **TSSOP-24** package, this component provides **16-bit parallel I/O expansion** via an **I²C-bus interface**, making it an efficient solution for applications requiring additional GPIO pins.  

Featuring **quasi-bidirectional ports**, the PCF8575PW allows each pin to function as either an input or output without requiring a separate data direction register. This simplifies system design while maintaining flexibility. The device operates at **2.5V to 6V**, ensuring compatibility with a wide range of logic levels.  

Key applications include **industrial control systems, LED displays, sensor interfacing, and keyboard scanning**, where expanding I/O resources is essential. The built-in **interrupt output** pin enhances efficiency by notifying the host microcontroller of input state changes, reducing polling overhead.  

With its **low standby current consumption**, the PCF8575PW is suitable for **battery-powered devices**. Its robust design ensures reliable performance in various environments, making it a practical choice for engineers seeking scalable I/O expansion.  

For detailed specifications, consult the official datasheet to ensure proper integration within your design.

Application Scenarios & Design Considerations

Remote 16-Bit I2C and SMBus I/O Expander with Interrupt Output 24-TSSOP -40 to 85

Alternative Part Number

  • TCA9535PWR --: 16-bit I2C I/O expander with interrupt output, pin-compatible function and similar PW package, direct functional replacement for PCF8575.
  • PCA9555PW --: 16-bit I2C/SMBus I/O expander in TSSOP package, widely used as a drop-in alternative to the PCF8575 with compatible register map.
  • MAX7311AUG+ --: 16-bit I2C port expander with interrupt, similar functionality and supply range, suitable alternative when TI part is unavailable.
