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.
