Figure 5 shows the internal circuit of one channel of the IH5352. Here, a shunt switch is closed, and the two series switches are open when the video switch channel is open or off. This provides much better isolation between the input and output terminals than a simple series switch does, especially at high frequencies. The result is excellent offisolation i.
