LTC4313CMS8-3#PBF - I2C Bus Buffer with Rise Time Accelerators from Linear Technology

The LTC4313CMS8-3#PBF is a high-performance, hot-swappable I2C bus buffer that enhances the capabilities of the I2C communication bus for networking multiple devices over long distances or in noisy environments. This device from Linear Technology is designed with advanced features to ensure robust communication and to improve system reliability.

Key Features:

• Two-Channel Bidirectional Buffer: The LTC4313CMS8-3#PBF provides two independent bidirectional channels, enabling it to connect multiple segments of an I2C bus. This feature allows for the expansion of I2C bus configurations beyond the typical limitations of a single bus segment.
• Rise Time Accelerators: The device includes rise time accelerators which significantly improve the transition times on the I2C bus signals. This results in faster data transfer rates and improved performance, especially in capacitive-loaded or long cable applications.
• Hot-Swap Capability: With its hot-swappable design, the LTC4313CMS8-3#PBF allows devices to be inserted into or removed from a live backplane without turning off the system power, minimizing downtime and maintenance complexity.
• Strong Noise Protection: The buffer provides superior noise protection on the data lines, ensuring high signal integrity even in the presence of external electrical noise that can be common in industrial environments.
• Prevents SDA and SCL Corruption: The LTC4313CMS8-3#PBF has built-in features to prevent SDA and SCL corruption during live board insertion and removal in backplane applications.
• Wide Operating Voltage Range: It supports a wide operating voltage range from 2.9V to 5.5V, making it suitable for various I2C applications and ensuring compatibility with both standard and low-voltage I2C devices.
• Flow-Through Pinout: The flow-through pinout simplifies PCB layout and reduces crosstalk by separating input and output SDA and SCL lines.
• MSOP-8 Package: The LTC4313CMS8-3#PBF comes in a compact MSOP-8 package, which is ideal for space-constrained applications without compromising performance.
