Overview
AN501 Vishay Siliconix The DG535/536 Wideband Multiplexers Suit a Wide Variety of Applications 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: S Digital switching S Audio Switching S PCM routing networks S ATE systems S High-channel-density multiplexing or demultiplexing systems S High-speed multiplexing systems S Low-level signal multiplexing Product Description A 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.
