LTC4309CDE#TRPBF Description

Short technical summary and product information.

The LTC4309CDE#TRPBF by LT is a hot-swappable 2-wire bus buffer that 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 data rate of 400 kHz and an ESD rating of 6 kV. The device operates within a temperature range of 0°C to 70°C. It offers level translation from 1.8V to 2.3V/5.5V and requires two supplies. The buffer offset is typically 60mV.

 

This bus buffer includes a stuck bus recovery feature, which attempts to free the bus if SDAOUT or SCLOUT are low for 30ms. It also supports rise-time acceleration for high capacitively loaded busses. The LTC4309CDE#TRPBF is supplied in a DFN-12 package.

 

Designed for high availability systems, this component is suitable for applications requiring robust I2C or SMBus communication during live system modifications.
