SN74S257DE4 Product Details

SN74S257DE4 Overview


As a means of saving space, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).The package is in the form of Tube.As far as mounting is concerned, digital switch ic uses Surface Mount.the multiplexers uses IC Multiplexer as the analog IC.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at 0°C~70°C.Designers have greater flexibility using digital controlled switch when it works with 4.75V~5.25V voltage.As a member of 74S series, the multiplexers can be used for a wide range of applications.There are 16 terminations included in its basic configuration.There is a base part number of 74S257 which can also be used in order to locate the logic switch that are related to this item.The multiplexer's system is supplied with a voltage of 5V.A component pin count of 16 is found on this turn signal switch.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.Its supply type is Single, which is used as the source of power.A configuration of 16 pins is used.The multiplexer ic is mounted in the direction of Surface Mount.There is a family of S members.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 4.75V.In order to maintain mux switch's normal operation, power is provided to 5V.The turn signal switch operates with 1 outputs.The multiplexers have 2 input lines used to accept voltage levels.
