Detailed Description
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 off-
isolation in the Video and RF frequency ranges when
compared to conventional analog switches.
The control input level shifting circuitry is very similar to that
of the IH5140 series of Analog Switches, and gives very high
