Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

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)
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.
Control Inputs Compatible with TTL Level
Applications
Y/C Video or CVBS Video Switch in LCD, Plasma,
and Projector Displays

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.
