FSAV331
Dual Channel 4:1 Video Switch
General Description
Features
The Fairchild video switch FSAV331 is a dual 4:1 high speed
video switch which can be configured as either multiplexer or
demultiplexer. Low On Resistance allows inputs to be con-
nected to outputs without adding propagation delay or generat-
ing additional ground bounce noise.
Wide bandwidth: 300 MHz
73 dB non adjacent channel crosstalk at 10MHz
56 dB Off Isolation at 10MHz

typical On Resistance (R
)

When the OE Pin is LOW, S and S connect the A Port to the
0
1
Low power consumption (3uA maximum)
Control input: TTL compatible
selected B Port output. When the OE Pin is HIGH, the switch is
OPEN and a HIGH-Impedance state exists between the two
ports.
Applications
Y/C video or CVBS video switch in LCD, plasma,
and projector displays

Note 1: 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 2: The input and output negative voltage ratings may be exceeded if the input
and output diode current ratings are observed.
Note 3: Unused control inputs must be held HIGH or LOW. They may not float.
DC Electrical Characteristics All typical value are for V = 5V @ 25 C unless otherwise specified.
