FSAV331
Dual Channel 4:1 Video Switch
General Description
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.
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
O Wide bandwidth: 300 MHz
O 73 dB non adjacent channel crosstalk at 10MHz
O 56 dB Off Isolation at 10MHz
O 3: typical On Resistance (R_ON)
O Low power consumption (3uA maximum)
O Control input: TTL compatible
Applications
O Y/C video or CVBS video switch in LCD, plasma,
and projector displays
