The LTC4304CMS#TRPBF from Analog Devices is a hot-swappable 2-wire bus buffer that enables I/O card insertion into a live backplane without data corruption. It offers bidirectional buffering for SDA and SCL lines, isolating backplane and card capacitances.
This device supports I2C, I2C Fast-Mode, and SMBus standards up to 400kHz operation. Key features include automatic disconnect and recovery for stuck buses (SDAOUT or SCLOUT low for ≥30ms), a fault flag, and 1V precharge on SDA/SCL lines during insertion to minimize disturbances. It operates within a voltage range of 2.7V to 5.5V and has a maximum data rate of 400kHz.
The LTC4304CMS#TRPBF is available in a 10-MSOP package and is suitable for applications requiring robust communication on a 2-wire bus, such as servers and RAID systems. It also includes ±15kV HBM ESD protection and rise-time accelerators controlled by the ACC input.
Mounting is surface mount. The operating temperature range is 0°C to 70°C, with a factory pack quantity of 2500.
