AN5010 - TV ELECTRONIC CHANNEL SELECTION CIRCUIT
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 swi.
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 adopte.
