The reason it is provided is that the board space can be saved by placing digital switch in the 20-TSSOP (0.173, 4.40mm Width).Tape & Reel (TR) is the method used for packaging.As far as mounting is concerned, digital switch ic uses Surface Mount.The analog IC used in the multiplexers can be referred to as Bus Switch.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.Using a 4.75V~5.25V supply voltage provides digital controlled switch's superior flexibility for designers.There is a base part number 3244 that can be used to locate signal switch's related components as well.
