DESCRIPTION The STMUX1000L is a 16 to 8 Bit multiplexer/ demultiplexer low RON bidirectional LAN Switch designed for various standard, such as 10/100/ 1000 Ethernet.
It is designed for very low Cross Talk, low bit to bit skew and low I/O capacitance. The differential signal from the Gigabit Ethernet Transceiver is multiplexed in one of two selected output while the unselected switch go to Hi-Z s t at us . The device integrates three 16 switches, S.P.D.T. (Single Pole Dual Throw Channel), for LED supporting.
