1622” TFT TV Service Manual 13/10/200411.14. PI5V33011.14.1. General descriptionPericom Semiconductor’s PI5V series of mixed signal video circuits are produced in the Company’sadvanced CMOS low-power technology, achieving industry leading performance.The PI5V330 is a true bidirectional Quad 2-channel multiplexer/demultiplexer that is recommended for bothRGB and composite video switching applications. The VideoSwitch™ can be driven from a current outputRAMDAC or voltage output composite video source.Low ON-resistance and wide bandwidth make it ideal for video and other applications. Also this device hasexceptionally high current capability which is far greater than mostanalog switches offered today. A single 5V supply is all that is required for operation.The PI5V330 offers a high-performance, low-cost solution to switch between video sources. Theapplication section describes the PI5V330 replacing the HC4053 multiplier and buffer/amplifier.11.14.2. Features• High-performance, low-cost solution to switch between video sources• Wide bandwidth: 200 MHz• Low ON-resistance: 3W• Low crosstalk at 10 MHz: –58 dB• Ultra-low quiescent power (0.1 μA typical)• Single supply operation: +5.0V• Fast switching: 10 ns• High-current output: 100 mA• Packages available:– 16-pin 300-mil wide plastic SOIC (S)– 16-pin 150-mil wide plastic SOIC (W)– 16-pin 150-mil wide plastic QSOP (Q)11.14.3.
