Description

The STMUX1800E is a 16 to 8-bit

multiplexer/demultiplexer low R

LAN switch designed for various standards, such

as 10/100/1000 Ethernet. It is designed for very

low crosstalk, low bit-to-bit skew and low I/O

capacitance.

The differential signal from the Gigabit Ethernet

transceiver is multiplexed into one of two selected

outputs while the unselected switch goes to Hi-Z

status.

The device integrates three SPDT (single pole

dual throw) switches, for LED support.

The device can be put into Low Power mode

consuming minimum power.
