The LTC4315CDE#TRPBF is a hot-swappable 2-wire bus buffer that provides bidirectional buffering, while maintaining a low offset voltage and high noise margin up to 0.3 • VCC. The high noise margin allows the LTC4315 to be interoperable with devices that drive a high VOL (>0.4V) and allows multiple LTC4315s to be cascaded. The LTC4315 supports level translation between 1.5V, 1.8V, 2.5V, 3.3V and 5V busses.
During insertion, the SDA and SCL lines are precharged to 1V to minimize bus disturbances. Connection is established between the input and output after ENABLE is asserted high and a stop bit or bus idle condition has been detected on the SDA and SCL pins.
If both data and clock are not simultaneously high at least once in 45ms and DISCEN is high, a FAULT signal is generated indicating a stuck bus low condition and the input is disconnected from the output. Up to 16 clock pulses are subsequently generated to free the stuck bus. A three state ACC pin enables input and output side rise time accelerators of various strengths.
