FSAV331
Dual 4:1 Wide Bandwidth Video Switch
General Description
The Fairchild video switch FSAV331 is a dual 4:1 high
speed video switch which can be configured as either mul-
tiplexer or demultiplexer. Low On Resistance allows inputs
to be connected to outputs without adding propagation
delay or generating additional ground bounce noise.
When the OE Pin is LOW, S
0
and S
1
connect the A Port to
the selected B Port output. When the OE Pin is HIGH, the
switch is OPEN and a HIGH-Impedance state exists
between the two ports.

Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
(Note 3)
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 guaranteed 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
CC
=
5V @ 25
C unless otherwise specified.
Note 4: 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 Ports).
