The DG535/536 Wideband Multiplexers
Suit a Wide Variety of Applications
IntroductionAnalog switch IC’s traditionally have found limited use in
applications involving high-frequency analog or digital signals.
Degradation of switch performance and intolerable signal
cross-talk between channels has undoubtedly forced many
designers to use bulky electromechanical switches or costly
discrete designs.
At best, analog switch ICs configured in L or T arrangement could
be adopted. However, increased board space and layout
complexity became major problems in configuring systems with
high channel density.
The DG535/536 are compact 16-channel, single-ended
multiplexer ICs, primarily designed as a cost-effective solution to
video and wideband switching problems. Other applications that
benefit from the devices’ superior performance characteristics
are: Digital switching Audio Switching PCM routing networks ATE systems High-channel-density multiplexing or demultiplexing systems High-speed multiplexing systems Low-level signal multiplexing
Product DescriptionA functional block diagram of the DG535/536 is shown in
Figure 1 and the switch configuration is shown in Figure 2. The
device is fabricated using self-isolated, silicon-gate D/CMOS
technology. This process enables the logic interface and driver
circuitry, the gating and latching stages, and the switching
elements to be combined in a monolithic structure.
Ease of design for large switching matrices and interface with
microprocessors is accomplished with comprehensive logic
gating and latching functions available on the chip.CS
