DM74AS257M Overview
It is included in the 16-SOIC (0.154, 3.90mm Width) in order to save board space.As a result, it is packaged in a way that is referred to as Tube.digital switch ic uses the method of Surface Mount for mounting.As the analog part, the circuit uses an analog IC Multiplexer.A temperature of 0°C~70°C will not leave the turn signal swturn signal switchch susceptible to external influences.The turn signal switch is designed for use with a 4.5V~5.5V supply voltage, which gives it a lot of flexibility.Multiplexers of the 74AS series can be used in a wide range of applications.Among its basic features are 16 terminations.In this case, 5V is the voltage supplied to the multiplexer's system.In this turn signal switch, there are 16 component pins.It is the end of conductors that is represented by GULL WING.The AS family includes the logic switch.It is recommended that the minimum supply voltage (Vsup) be kept at 4.5V to avoid some unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 5.5V in order to prevent some unnecessary failures.The turn signal switch operates with 1 outputs.This multiplexer has a total of 2 inputs.
