Description
The STMUX7000 is a 7-channel
multiplexer/demultiplexer low RON bidirectional
designed for analog video signal, such as VGA. It
is designed for very low crosstalk, and high
bandwidth to maintain high signal integrity.
The analog video signal multiplexed from one of
two selected sources in the notebook and docking
station while the unselected switch goes to Hi-Z
status.
The device is also protected against high ESD
that supports up to 8 kV contact on all I/O pins.
The device can be put into low power mode
consuming minimum power.
