FSAV433
Low Voltage Ultra Low Power
High Bandwidth (550MHz) 3-Port 3:1 Video Switch
General Description
The FSAV433 is an ultra low power high bandwidth video
switch specially designed for the switching of three analog
video signals, including computer RGB and high definition
YPbPr signals. The wide bandwidth (550MHz) of this
switch allows signal passage with minimum edge and
phase distortion while
85dB non
adjacent channel
crosstalk generates negligible image noise between active
channels. Optimized differential gain and differential
phases maintain the image integrity of video applications
while low On Resistance offers low signal insertion loss.

Absolute Maximum Ratings
(Note 2)
Recommended Operating
Conditions
(Note 4)
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.
DC Electrical Characteristics
Note 5: Typical values are at T

q
C
Note 6: Measured by the voltage drop between A and B pins at the indicated current through the switch. On Resistance is determined by the lower of the
voltages on the two (A or B) pins.
