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

Vishay Siliconix proprietary D/CMOS process. Each switch

conducts equally well in both directions when on.
