Description and Introduction

8-bit I2C and SMBus I/O port with 2-kbit EEPROM The **PCA9500** from Philips is a versatile **I²C bus repeater** designed to extend the range and reliability of I²C communication systems. It serves as a bidirectional buffer, enabling seamless signal transmission between different voltage domains while maintaining signal integrity.  

Featuring **automatic direction sensing**, the PCA9500 eliminates the need for additional control signals, simplifying system design. It supports **voltage level translation** between 2.3V and 5.5V, making it ideal for mixed-voltage applications. The device also incorporates **rise time accelerators**, which enhance signal speed on heavily loaded buses, ensuring robust performance in demanding environments.  

With **low standby current consumption**, the PCA9500 is well-suited for power-sensitive applications. Its compact footprint and ease of integration make it a practical solution for industrial, automotive, and consumer electronics where reliable I²C communication is critical.  

Key features include:  
- Bidirectional I²C and SMBus repeater  
- Voltage level translation (2.3V to 5.5V)  
- Automatic direction control  
- Rise time acceleration for improved signal integrity  

The PCA9500 is a reliable choice for designers seeking to enhance I²C bus performance while maintaining compatibility with existing systems. Its robust design ensures stable operation in a wide range of applications.
