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, S₀ and S₁ 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.
Features
s Wide bandwidth: 300 MHz
s −73 dB non adjacent channel crosstalk at 10MHz
s −56 dB Off Isolation at 10MHz
s 3Ω typical On Resistance (R_ON)
s Low power consumption (3uA maximum)
s Control input: TTL compatible
Applications
• Y/C video or CVBS video switch in LCD, plasma, and
projector displays
