5-Channel 2:1 Analog Mux/Demux

The QS4A201 is a high-performance CMOS two-by-two analog cross point switch. This device provides two sets of five high-speed CMOS switches providing "cross point" connection between inputs and outputs. The QS4A201 with 1.3GHz bandwidth makes it ideal for high-performance video signal switching, audio signal switching, and telecomm routing applications. High performance and low power dissipation makes this device ideal for battery operated and remote instrumentation applications. The QS4A201 operates at -40C to +85C.
