Revised January 2005 FSAV332 Wide Bandwidth Video Switch General Description Features 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. ■ Wide bandwidth: 368 MHz 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. ■ −84 dB non adjacent channel crosstalk at 10MHz ■ −49 dB Off Isolation at 10MHz ■ 3Ω typical On Resistance (RON) ■ Low power consumption (3uA maximum) ■ 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 FSAV332QSC MQA16 16-Lead Quarter Size Outline Package (QSOP), JEDEC MO-137, 0.150" Wide FSAV332MTC MTC14 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide FSAV332MTC_NL MTC14 Pb-Free 14-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices 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” 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 @ 25°C unless otherwise specified.
