The reason it is provided is that the board space can be saved by placing digital switch in the 16-SSOP (0.154, 3.90mm Width).As a result, it is packaged in a way that is referred to as Tape & Reel (TR).The mounting method digital switch ic uses is Surface Mount.For the analog part of the multiplexers, an IC Multiplexer is used.By keeping the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.As a member of 74FCT series, the multiplexers can be used for a wide range of applications.The base part number is 74FCT257, so you can find its logic switch related parts using that number.
