SN74ALS857DWR Overview


Due to the lack of space on the board, digital switch is provided in the 24-SOIC (0.295, 7.50mm Width).Tape & Reel (TR) is the method used for packaging.The mounting method digital switch ic uses is Surface Mount.Multiplexer is the analog IC that the multiplexers uses.If the operating temperature is maintained at 0°C~70°C, turn signal switch will not be susceptible to external factors.With a supply voltage of 4.5V~5.5V, designers have greater flexibility of digital controlled switch.Since they are members of the 74ALS series, they can be used in a wide variety of applications.The basic configuration includes 24 terminations.The multiplexer's system is supplied with a voltage of 5V.This turn signal switch has a total of 24 component pins.At the end of a conductor, it uses GULL WING as the point where the conductor ends.There is a family of ALS members.Vsup should be kept at 4.5V to prevent some unnecessary failures.Avoid unnecessary failures by keeping Vsup at 5.5V.For the turn signal switch's operation, there are 1 outputs.The multiplexer is equipped with 2 inputs.
