SN74S257N Overview
Due to the lack of space on the board, digital switch is provided in the 16-DIP (0.300, 7.62mm).Tube is the packaging method.digital switch ic uses the method of Through Hole for mounting.The analog IC in the multiplexers is identified as Multiplexer.The operating temperature of 0°C~70°C will not be susceptible to external factors.Designers have greater flexibility using digital controlled switch when it works with 4.75V~5.25V voltage.Several applications are possible for 74S series multiplexers.As parts of its basic configuration, 16 terminations are desgined.The base part number is 74S257, which can also be used to find its logic switch related parts.The voltage supplied for multiplexer's system is 5V.multiplexer's systemA component pin count of 16 is found on this turn signal switch.In this case, Single is employed as the supply type.The board has 16 pins configured.The multiplexer ic is mounted in the direction of Through Hole.There is a family of S members.Normally, 5V is powered by a battery.The turn signal switch contains 1 outputs designed to operate.With a supply voltage of 5V, reliable performance of the multiplexers can be achieved.This multiplexer is equipped with 8 inputs and 8 outputs.A voltage level can be inserted into the 2 input lines of multiplexers.This turn signal switch's circuit uses 4 transmission channels.
