PCF8574P, Remote 8-bit I/O Expander for I²C Bus, 2.5V to 6V, DIP16

The PCF8574P is a remote 8-bit I/O expander in a DIP16 package, designed to interface with the I2C bus, enabling additional digital I/O capabilities through a simple two-wire connection. This CMOS device provides eight quasi-bidirectional I/O pins, making it ideal for applications requiring expanded I/O such as controlling LEDs, sensors, or switches.

It features an open-drain interrupt output, which can alert the microcontroller when input data changes. With low power consumption, the PCF8574P is compatible with most microcontrollers, supporting multiple I/O expansion options through addressable hardware pins, allowing up to 8 devices on the same I2C bus.

Key Features :

• I2C Interface for I/O Expansion: Facilitates seamless integration with I2C-compatible microcontrollers.
• 8-Bit Quasi-Bidirectional I/O Port: Provides flexible I/O control for various applications.
• Wide Operating Voltage (2.5V to 6V): Broad power compatibility for diverse systems.
• Open-Drain Interrupt Output: Allows notification to the controller on input change events.
• Low Power Consumption: Operates with minimal current, suitable for energy-efficient designs.
• DIP16 Package: Easy through-hole mounting for prototyping and development.
