TYPICAL APPLICATION
FEATURES
DESCRIPTION
2-Wire Bus Buffer with
High Noise Margin
The LTC4315 is a hot-swappable 2-wire bus buffer
that provides bidirectional buffering, while maintain-
ing 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.
