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.

QFN
STMUX1000LQTR
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
status.
The device integrates three 16Ω switches,
S.P.D.T. (Single Pole Dual Throw Channel), for
LED supporting.
