The reason it is provided is that the board space can be saved by placing digital switch in the 16-SOIC (0.209, 5.30mm Width).Tape & Reel (TR) is the method used for packaging.Surface Mount is the mounting method digital switch ic uses.As the analog part, the circuit uses an analog IC Decoder/Demultiplexer.By maintaining the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 2V~6V, designers are provided with a greater degree of flexibility.The multiplexers from 74HC series can be used for a wide range of applications.To find signal switch's related components, a base part number of 74HC138 may also be used.If the supply voltage is set to 5V, reliable performance of the multiplexers can be achieved.
