The DG408 and DG409, new multiplexers from Vishay Siliconix, represent a new generation of high-performance multiplexers and demultiplexers with many specific improvements over existing products available today. Built with the company's high-voltage silicon-gate technology, these new ICs offer significantly reduced on-resistance (<100 W), leakage currents (IS(OFF) < 0.5 nA), power dissipation (2.25 mW), and much faster switching (250 ns) over older industry standards. These improved specifications allow designers to greatly reduce system errors and improve system performance.
