16-bit to 8-bit MUX/DEMUX for gigabit Ethernet LAN switch with LED switch and enhanced ESD protection
DescriptionThe STMUX1800L is a 16 to 8-bit multiplexer/demultiplexer low RON bidirectional 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.
