LTC4307IMS8

LTC4307IMS8 Description

The LTC4307IMS8 from Analog Devices Inc. is a high-performance I²C/SMBus accelerator and hot-swap buffer designed to enhance signal integrity and system reliability in multi-master I²C applications. Housed in an 8-pin MSOP package, this surface-mount device operates over a wide supply voltage range of 2.3V to 5.5V, making it compatible with both 3.3V and 5V systems. With a maximum data rate of 400kHz, it supports standard and fast-mode I²C communications while minimizing capacitive loading with an input capacitance of just 10pF. Its dual-channel architecture ensures robust buffering and signal conditioning for bidirectional data (SDA) and clock (SCL) lines.

LTC4307IMS8 Features

• Hot-Swap Capability: Enables live insertion/removal of I²C devices without bus corruption.
• Acceleration & Buffering: Reduces rise times and mitigates signal degradation in long or heavily loaded buses.
• Low Power Consumption: Draws only 8mA supply current, ideal for power-sensitive designs.
• Wide Voltage Range (2.3V–5.5V): Supports mixed-voltage systems without level shifters.
• ROHS3 Compliant & REACH Unaffected: Meets environmental and safety standards.
• High Noise Immunity: Robust performance in electrically noisy environments.

LTC4307IMS8 Applications
