MC74VHC257M Overview
Digital switch is provided in the 16-SOIC (0.209, 5.30mm Width) for the purpose of saving board space.As a result, it is packaged in a way that is referred to as Tube.As far as mounting is concerned, digital switch ic uses Surface Mount.As the analog part, the circuit uses an analog IC Multiplexer.If the operating temperature is maintained at -55°C~125°C, turn signal switch will not be susceptible to external factors.The turn signal switch is designed for use with a 2V~5.5V supply voltage, which gives it a lot of flexibility.Several applications are possible for 74VHC series multiplexers.As parts of its basic configuration, 16 terminations are desgined.In addition, it also has a base part number of 74VHC257, which can be used to find related parts.The multiplexer's system is powered by 3.3V voltage.A component pin count of 16 is found on this turn signal switch.GULL WING is used as the point at which the conductors come to an end as part of this formula.Single is employed as its supply type.The multiplexer ic is mounted in the direction of Surface Mount.I would like to refer to the logic switch as a member of the AHC/VHC family.The minimal supply voltage (Vsup) should be kept at 2V to avoid some unnecessary failures.To avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.mux switch's normal operation requires the power supply of 2/5.5V.It is provided with 2 inputs.The switches package is packaged in a way which is consistent with RAIL.For the purpose of accepting voltage levels, the multiplexers have 8 input lines.There are 4 output lines designed to serve as the source of the signal.
