74HC257DB,112 Overview
Digital switch is provided in the 16-SSOP (0.209, 5.30mm Width) for the purpose of saving board space.In this case, it is packaged as Tube.Digital switch ic uses a Surface Mount mounting method.the multiplexers uses IC Multiplexer as the analog IC.By maintaining the operating temperature at -40°C~125°C, turn signal switch will not be affected by external factors.It provides digital controlled switch's superior flexibility for designers to use when it operates with a supply voltage of 2V~6V.provides digital controlled switch's digital controlled switch'sSeveral applications are possible for 74HC series multiplexers.Among its basic features are 16 terminations.There is a base part number of 74HC257 which can also be used in order to locate the logic switch that are related to this item.In this case, 5V is the voltage supplied to the multiplexer's system.Currently, this turn signal switch has a total of 16 component pins.It is the end of conductors that is represented by GULL WING.As a type of supply, Single is employed.This multiplexer ic has 16 pins configured.As you can see, it is mounted in the direction of Surface Mount.The logic switch belongs to the family of HC/UH.The minimal supply voltage (Vsup) should be kept at 2V to avoid some unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 6V in order to prevent some unnecessary failures.In order for the turn signal switch to work, there are 4 outputs.With a supply voltage of 5V, reliable performance of the multiplexers can be achieved.It has 8 inputs.It is possible to accept voltage levels through 2 input lines of multiplexers.
