The LTC4303CDD#TRPBF from Analog Devices is a hot swappable 2-wire bus buffer that facilitates card insertion into live backplanes without corrupting data and clock buses. It provides bidirectional buffering, isolating backplane and card capacitances.
Key features include automatic disconnection of SDA/SCL lines if the bus remains low for over 30ms, and automatic clocking to recover stuck busses. The device offers ±15kV Human Body Model ESD protection and supports I2C, I2C Fast-Mode, and SMBus standards up to 400kHz operation. It also includes a 1V precharge on SDA and SCL lines to minimize bus disturbances during insertion.
The LTC4303CDD#TRPBF is available in MSOP 8-Pin and DFN (3mm x 3mm) packages. Its design prevents SDA and SCL corruption during live board insertion and removal, making it suitable for applications requiring robust interface management.
This bus buffer is ideal for systems where reliable hot-swapping is critical, such as servers and RAID systems, acting as a capacitance buffer and bus extender.
The device supports 5V and 3.3V operation.
It is available in MSOP 8-Pin and DFN (3mm x 3mm) packages.
The RoHS status is RoHS3 Compliant.
The MSL is 1 Unlimited.
It automatically disconnects SDA/SCL lines when the bus is stuck low for over 30ms and generates clock pulses to recover the bus.
It features ±15kV Human Body Model ESD protection.
It is compatible with standards up to 400kHz operation.
