FSAV332 — Quad Video Switch with Individual
Enables
Features
Wide Bandwidth: 368MHz
-84dB Non-adjacent Channel Crosstalk at 10MHz
-49dB Off-Isolation at 10MHz
3Ω Typical On Resistance (R
ON
)
Low-Power Consumption: 3µA Maximum
Control Input: TTL Compatible
Description
The FSAV332 video switch is a quad high-speed video
switch. Low on resistance allows inputs to be connected
to outputs without adding propagation delay or
generating additional ground bounce noise.
The device is organized as four one-bit switches with
separate output enable (/OE) pins. When OE is LOW,
the switch is ON and port A is connected to port B.
When OE 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, or 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.

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.
