LTC4315
2-Wire Bus Buffer with
High Noise Margin
FEATURES DESCRIPTION n The LTC4315 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. Bidirectional Buffer Increases Fanout
