Shipping overseas is convenient due to the electrical component's packing in 20-SOIC (0.295, 7.50mm Width). This packaging method provides high reliability because it uses advanced packaging techniques. The multiplexer is located in Surface Mount. Multiplexers and demultiplexers have the same number of circuits 2:1. Operating temperature around -40°C~85°C TA extended. An electrical component like this is included in the 20 series. On the other hand, analog switches can be constructed using SPDT switching circuits. The circuits in this analogue multiplexer number 4. Look for analog switch ic variants by searching with ISL8394.
