PCF8574T SOIC-16 (SOP-16) NXP

Description: The PCF8574T is an 8-bit remote input/output (I/O) expander that communicates through the I²C bus. It allows a microcontroller to add eight extra digital GPIO pins using only two communication lines (SDA and SCL), making it ideal for projects with limited GPIO availability.

Key Features:

8-bit bidirectional GPIO expansion

I²C interface (2-wire communication)

Low power consumption

Wide operating voltage

Interrupt output for input change detection

SOP-16 package

Applications:

Arduino and ESP32 projects

Raspberry Pi GPIO expansion

LCD 16×2/20×4 I²C interface modules

Industrial automation

Home automation

Keyboard and switch interfacing

LED control
