PCF8574RGTR General Description

The PCF8574RGTR is an 8-bit I/O expander for the I2C bus. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface serial clock (SCL) and serial data (SDA). This device features an open-drain output, which can be used for interfacing with various logic levels.The PCF8574RGTR has an operating voltage range of 2.5V to 6V, making it suitable for a wide range of applications. It has a maximum I2C bus speed of 100 kHz and comes in a small TSSOP package, making it ideal for space-constrained designs.This I/O expander is commonly used in applications where a microcontroller has limited I/O pins available and needs to interface with multiple devices. It can be used in industrial control, home automation, and other embedded systems where additional I/O capability is required.
