Description
4-channel Wideband And Video Multiplexer
Manufacturer
Intersil Corporation
Datasheet
4-Channel Wideband and Video
Multiplexer
The HI-524 is a 4-Channel CMOS analog multiplexer designed
to process single-ended signals with bandwidths up to 10MHz.
The chip includes a 1 of 4 decoder for channel selection and an
enable input to inhibit all channels (chip select).
Three CMOS transmission gates are used in each channel,
as compared to the single gate in more conventional CMOS
multiplexers. This provides a double barrier to the unwanted
coupling of signals from each input to the output. In addition,
Dielectric Isolation (DI) processing helps to insure the
Crosstalk is less than -60dB at 10MHz.
The HI-524 is designed to operate into a wideband buffer
amplifier such as the Intersil HA-2541. The multiplexer chip
includes two “ON” switches in series, for use as a feedback
element with the amplifier. This feedback resistance
matches and tracks the channel ON resistance, to minimize
the amplifier V
The HI-524 is well suited to the rapid switching of video and
other wideband signals in telemetry, instrumentation, radar
and video systems.
