Description and Introduction

4-bit I2C-bus and SMBus I/O port The **PCA9536DP** from NXP Semiconductors is a versatile, low-voltage 4-bit I²C and SMBus I/O expander designed to simplify digital interface expansion in embedded systems. This compact device provides four configurable general-purpose input/output (GPIO) pins, enabling seamless communication between microcontrollers and peripheral components.  

Operating at a supply voltage range of **2.3V to 5.5V**, the PCA9536DP is suitable for a variety of applications, including industrial controls, consumer electronics, and IoT devices. Its I²C-compatible interface supports standard (100 kHz) and fast-mode (400 kHz) communication, ensuring efficient data transfer.  

Key features include programmable polarity inversion, interrupt output for monitoring pin state changes, and low standby current consumption, making it ideal for power-sensitive designs. The device also offers internal pull-up resistors, reducing the need for external components.  

Housed in an **8-pin TSSOP package**, the PCA9536DP provides a space-efficient solution for expanding I/O capabilities without increasing PCB complexity. Its robust design ensures reliable performance in diverse environments, making it a practical choice for engineers seeking a simple yet effective GPIO expansion solution.  

With its ease of integration and flexible configuration, the PCA9536DP is a valuable component for enhancing system functionality while maintaining design efficiency.
