The LTC4307CMS8#TRPBF is a signal buffer manufactured by Analog Devices. It features low-offset I2C bus buffering and is designed to improve the Performance of I2C devices. It operates from a single supply source of 2.7V to 5.5V, and supports I2C communications up to 3.4 Mbps. The device has an operating temperature range of -40°C to +85°C and features open-drain outputs. It is designed to eliminate signal reflections, reduce loading on I2C lines, increase power supply noise immunity, and improve I2C device signal integrity and accuracy. This device can also be used to protect the total I2C bus by preventing harmful interference from external noise sources. It provides an enhanced level of system robustness and protection when used in critical or harsh environments.
