FSAV331 — Dual-Channel, 4:1 Video Switch
Features
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 connected to outputs without adding
propagation delay or generating additional ground
bounce noise.
Wide Bandwidth: 300MHz
-73dB Non-Adjacent Channel Crosstalk at 10MHz
-56dB Off Isolation at 10MHz
On Resistance: 3Ω (Typical)
Low Power Consumption: 3µA (Maximum)
Control Inputs Compatible with TTL Level
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.
Applications
Y/C Video or CVBS Video Switch in LCD, Plasma,
and Projector Displays

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.
