4-Channel Wideband and VideoMultiplexer

TheHI-524isa4-ChannelCMOSanalogmultiplexerdesignedtoprocesssingle-endedsignalswithbandwidthsupto10MHz.Thechipincludesa1of4decoderforchannelselectionandanenable input to inhibit all channels (chip select).

Three CMOS transmission gates are used in each channel,ascomparedtothesinglegateinmoreconventionalCMOSmultiplexers.Thisprovidesadoublebarriertotheunwantedcouplingofsignalsfromeachinputtotheoutput.Inaddition,Dielectric Isolation (DI) processing helps to insure theCrosstalk is less than -60dB at 10MHz.

The HI-524 is designed to operate into a wideband bufferampli er such as the Intersil HA-2541. The multiplexer chipincludes two “ON” switches in series, for use as a feedbackelement with the ampli er. This feedback resistance

matches and tracks the channel ON resistance, to minimizethe ampli er VOS and its variation with temperature.The HI-524 is well suited to the rapid switching of video andother wideband signals in telemetry, instrumentation, radarand video systems.
