LTC4309CGN#TRPBF Description

Short technical summary and product information.

The LTC4309CGN#TRPBF is a hot-swappable 2-wire bus buffer from Linear Technology (LT) that enables I/O card insertion into live backplanes without corrupting data and clock busses. It offers bidirectional buffering, isolating backplane and card capacitances. This device features a low offset of 60mV, high VOL tolerance, and supports cascading multiple devices. The LTC4309CGN#TRPBF includes a stuck bus recovery mechanism that detects if SDAOUT or SCLOUT are low for 30ms, pulling FAULT low and attempting to free the bus by generating clock pulses and a stop bit.

 

Key electrical specifications include a data rate of 400 kHz and an ESD rating of 6 kV. It functions as a bus buffer and rise time accelerator, supporting I2C hot-swapping. The level translation capabilities range from 1.8V to 2.3V/5.5V, and it operates with two supply voltages. The device is available in a 16-pin SSOP package and operates within a temperature range of 0°C to 70°C.

 

This bus buffer is suitable for high availability computing, networking, and data storage systems that utilize I2C or SMBus for system management. Its design addresses challenges like increased capacitive load on the bus and the need for robust communication during live board insertion and removal.
