FSAV450  
800MHz 4 Channel 2:1 Video Switch  
General Description  
Features  
The FSAV450 is a high performance Quad SPDT (2-to-1 multi-  
plexer/demultiplexer) video switch designed specifically for  
switching high definition YPbPr and computer RGB (up to  
UXGA) signals. The bandwidth of this device is 800MHz (Typ)  
which allows signals to pass with minimal edge and phase dis-  
tortion. Image integrity is maintained with low crosstalk, high  
OFF-Isolation and low differential gain and phase. The low On  
Resistance (4 typical) minimizes signal insertion loss. Low  
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 guaran-  
teed 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.
