产品概述
描述
The STMUX1800E is a 16 to 8-bit multiplexer/demultiplexer low RONbidirectional 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.
