Description
The DG540/541/542 are high performance monolithic
wideband/video switches designed for switching RF, video
and digital signals. By utilizing a “T” switch configuration
on each channel, these devices achieve exceptionally low
crosstalk and high off-isolation. The crosstalk and
off-isolation of the DG540 are further improved by the
introduction of extra GND pins between signal pins.
To achieve TTL compatibility, low channel capacitances
and fast switching times, the DG540 family is built on the
Siliconix proprietary D/CMOS process. Each switch
conducts equally well in both directions when on.
