LTC4315CMS#PBF

LTC4315 is a hot-swappable 2-wire bus buffer. It provides bidirectional buffering, while maintaining a low offset voltage and high noise margin upto 0.3VCC. During insertion, the SDA and SCL lines are precharged to 1V to minimize bus disturbances. Connection is established between the input and output after ENABLE is asserted high and a stop bit or bus idle condition has been detected on the SDA and SCL pins. It is widely used in application such as capacitance buffers/bus extender, live board insertion, telecommunications systems including ATCA, level translation, PMBus, servers etc.

• Compatible with non-compliant I²C devices that drive a high VO
• Selectable rise time accelerator current
• Level shift 1.5V, 1.8V, 2.5V, 3.3V and 5V busses
• Stuck bus disconnect and recovery
• Compatible with I²C, I²C fast mode and SMBus
• ±4KV human body model ESD ruggedness
• High impedance SDA, SCL pins when unpowered
• Prevents SDA and SCL corruption during live board insertion and removal from backplane
• Operating temperature is 0°C to 70°C
• Packaging style is 12-lead plastic MSOP
