74VHC257MTR Overview
In order to conserve board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).It is packaged in the way of Tape & Reel (TR).For mounting, digital switch ic uses the method Surface Mount.the multiplexers 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.Designers have greater flexibility when digital controlled switch operates at a 2V~5.5V supply voltage.The multiplexers can be used for a wide range of applications since they are members of 74VHC series.Among its basic configurations are 16 terminations.The base part number is 74VHC257, so you can find its logic switch related parts using that number.The multiplexer's system is powered by 3.3V voltage.In this turn signal switch, there are 16 components that can be connected to each pin.At the end of a conductor, it uses GULL WING as the point where the conductor ends.There is a type of supply Single that is employed in this case.A total of 16 pins are configured on this board.The multiplexer ic is mounted in the direction of Surface Mount.The logic switch object belongs to the family of AHC/VHC.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 5.5V so as to avoid some unnecessary failures.During mux switch's normal operation, 2/5.5V is provided with a power supply.The switches is packaged according to the way of TAPE AND REEL.Signal source consists of 1 output lines.To ensure that the digitalswitch performs properly, 4 circuits are formed.
