Vishay Siliconix
Wideband/Video “T” Switches
DESCRIPTION
The DG540, DG541, DG542 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 Vishay
Siliconix proprietary D/CMOS process. Each switch
conducts equally well in both directions when on.
