It is included in the 24-DIP (0.600, 15.24mm) in order to save board space.Tube represents its packaging.The mounting method digital switch ic uses is Through Hole.Decoder/Demultiplexer is the analog IC that the multiplexers uses.The operating temperature will not be affected by external factors when turn signal switch is set to -40°C~125°C.With a supply voltage of 4.5V~5.5V, designers have greater flexibility of digital controlled switch.With the 74HCT series, the multiplexers are suitable for a diverse range of applications.The basic configuration includes 24 terminations.There is a base part number 74HCT154 that can be used to locate signal switch's related components as well.For multiplexer's system, a voltage of 5V is supplied.A component pin count of 24 is found on this turn signal switch.Among the family of HCT the logic switch is a member.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 4.5V.In order to avoid some unnecessary failures, you should maintain a maximum supply voltage (Vsup) of 5.5V.During mux switch's normal operation, 5V is provided with a power supply.I would classify the digital switch ic as an electronic part belonging to the Decoder/Drivers category.Also, it provides an improved version of the characteristics of 2 ENABLE INPUTS.
