FSAV430 Low Voltage 1.1GHz 4 Channel 2:1 Video Switch
December 2004
Revised August 2005
General Description
The FSAV430 is a high performance Quad SPDT (2-to-1 multiplexer/demultiplexer) video switch designed specifically for
switching high definition YPbPr and computer RGB (up to
UXGA) signals. The bandwidth of this device is 1.1GHz (Typ)
which allows signals to pass with minimal edge and phase distortion. Image integrity is maintained with low crosstalk, high
OFF-Isolation and low differential gain and phase. The low On

Resistance (4.5
voltage operation (3V), low power consumption (1uA maximum)
and small scale packaging (including leadless DQFN) make this
device ideal for a broad range of applications.

Note 2: The Absolute Maximum Ratings are those values beyond which the safety of
the device cannot be guaranteed. The device should not be operated at these limits.
The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. The Recommended Operating Conditions
tables will define the conditions for actual device operation.
Note 3: The input and output negative voltage ratings may be exceeded if the input
and output diode current ratings are observed.
Note 4: Unused control inputs must be held HIGH or LOW. They may not float.
