FSAV332 Quad Video Switch with Individual Enables
April 2004
Revised July 2005
General Description
The Fairchild video switch FSAV332 is a quad high speed
video switch. Low On Resistance a llows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.
The device is o rganized as four 1-bit switches wi th separate output enable (OE) pins. Whe n 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.
Features
O
Wide bandwidth: 368 MHz
O
84 dB non adjacent channel crosstalk at 10MHz
O
49 dB Off Isolation at 10MHz
O3:
typical On Resistance (RON)
O
Low power consumption (3uA maximum)

Control input: TTL compatible
Applications
• Y/C video or CVBS video switch in LCD, plasma, and
projector displays

Note 1: The “Absolute Maximum Ratings” are those value s beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these lim its. The parametric values defin ed in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “Recomm ended O peratin g Con ditions ” table will defin e the condition s
for actual device operation.
Note 2: The input and output negative voltage ratings may be exceeded if
the input and ou t put diode current ratings are obser v ed.
Note 3: Unused control inputs m ust b e held H IGH o r LOW. They may n ot
float.
