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.
