Introduction
Analog 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
