The LTC4300A-1CMS8#TRPBF is a hot swappable 2-wire bus buffer designed by Analog Devices. This component allows for I/O card insertion into a live backplane without corrupting data and clock busses. It provides bidirectional buffering, isolating backplane and card capacitances.
Key features include a supply voltage range of 2.7V to 5.5V and a maximum data rate of 400kHz, compatible with I2C, I2C Fast Mode, and SMBus standards. The device incorporates rise-time accelerator circuitry and precharges SDA and SCL lines to 1V during insertion to minimize bus disturbances. It also supports clock stretching, arbitration, and synchronization.
The LTC4300A-1 variant includes a CMOS threshold digital ENABLE input pin for low current mode and an open drain READY output pin. The device is available in a compact 8-MSOP package, suitable for surface mount applications.
This buffer is ideal for applications requiring robust I2C communication during live board insertion and removal, such as in servers and desktop computers.
