74AHC257PW,118 Overview


In order to save board space, digital switch is located in the 16-TSSOP (0.173, 4.40mm Width).It is packaged in the way of Tape & Reel (TR).For mounting, digital switch ic uses the method Surface Mount.the multiplexers uses IC Multiplexer as the analog IC.The operating temperature will not be affected by external factors when turn signal switch is set to -40°C~125°C.When operated with a 2V~5.5V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.In addition to being a member of the 74AHC series, these multiplexers have a wide range of applications.This configuration includes 16 terminations as part of its basic functionality.There is a base part number of 74AHC257 which can also be used in order to locate the logic switch that are related to this item.The multiplexer's system is powered by 5V voltage.This turn signal switch has 16 component pins.It is the end of conductors that is represented by GULL WING.This supply type employs Single.This multiplexer ic is configured with 16 pins.As you can see, it is mounted in the direction of Surface Mount.The logic switch is a member of the AHC family.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 2V.Supply voltages of 5V can provide reliable performance of the multiplexers.It is possible to accept voltage levels through 8 input lines of multiplexers.A signal source has 4 output lines.
