FSAV450 — 800MHz, 4-Channel, 2:1 Video Switch
Features
Description
The FSAV450 is a high performance Quad Sinple-Pole
Double-Throw (SPDT) (2-to-1 multiplexer/ demultiplexer)
video switch designed specifically for switching high
definition YPbPr and computer RGB (up to UXGA)
signals. The bandwidth of this device is 800MHz
(typical) which allows signals to pass with minimal edge
and phase distortion. Image integrity is maintained with
low crosstalk, high off-Isolation and low differential gain
and phase. The low on resistance (4 typical) minimizes
signal insertion loss. Low voltage operation (3V), low
power consumption (1µA maximum) and small scale
packaging (including leadless DQFN) make this device
ideal for a broad range of applications.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Note:
1. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are
observed.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.
