FSAV332 Wide Bandwidth Video Switch
April 2004 Revised January 2005
FSAV332 Wide Bandwidth Video Switch
General Description
The Fairchild video switch FSAV32 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 1-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.
Features
s Wide bandwidth: 368 MHz s -84 dB non adjacent channel crosstalk at 10MHz s -49 dB Off Isolation at 10MHz s 3 typical On Resistance (RON) s Low power consumption (3uA maximum) s 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 values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 3: Unused control inputs must be held HIGH or LOW. They may not float.
DC Electrical Characteristics All typical values are for VCC = 5V @ 25C unless otherwise specified.
