FSAV331 Dual Channel 4:1 Video Switch
General 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. 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.
Features O Wide bandwidth: 300 MHz O 73 dB non adjacent channel crosstalk at 10MHz O 56 dB Off Isolation at 10MHz O 3: typical On Resistance (RON) O Low power consumption (3uA maximum) O Control input: TTL compatible Applications O 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 tables 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 value are for VCC = 5V @ 25qC unless otherwise specified.
