LTC4314
Pin-Selectable, 4-Channel,
2-Wire Multiplexer
with Bus Buffers
DESCRIPTION FEATURES n The LTC®4314 is a hot-swappable 4-channel 2-wire bus
multiplexer that allows one upstream bus to connect to
any combination of downstream busses or channels.
An individual enable pin controls each connection. The
LTC4314 provides bidirectional buffering, keeping the upstream bus capacitance isolated from the downstream bus
capacitances. The high noise margin allows the LTC4314
to be interoperable with I2C devices that drive a high VOL
(> 0.4V). The LTC4314 supports level translation between
1.5V, 1.8V, 2.5V, 3.3V and 5V busses. The hot-swappable
nature of the LTC4314 allows I/O card insertion into, and
removal from, a live backplane without corruption of the
data and clock busses. 1:4 Multiplexer/Switch for 2-Wire Bus
