Revised May 2004 FSAV331 Dual 4:1 Wide Bandwidth Video Switch General Description Features 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: 300 MHz 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. ■ Low power consumption (3uA maximum) ■ −73 dB non adjacent channel crosstalk at 10MHz ■ −56 dB Off Isolation at 10MHz ■ 3Ω typical On Resistance (RON) ■ Control input: TTL compatible Applications • Y/C video or CVBS video switch in LCD, plasma, and projector displays Ordering Code: Order Number Package Number Package Description FSAV331QSC MQA16 16-Lead Quarter Size Outline Package (QSOP), JEDEC MO-137, 0.150" Wide FSAV331MTC MTC16 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Device also available in Tape and Reel.

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 @ 25°C unless otherwise specified.
