DM74AS257N Overview
In order to save board space, digital switch is located in the 16-DIP (0.300, 7.62mm).Tube represents its packaging.In terms of mounting, digital switch ic uses the Through Hole method .Multiplexer is the analog IC that the multiplexers uses.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at 0°C~70°C.Using a 4.5V~5.5V supply voltage provides digital controlled switch's superior flexibility for designers.The multiplexers from 74AS series can be used for a wide range of applications.The basic configuration of this system includes 16 terminations.For multiplexer's system, 5V voltage is supplied.A component pin count of 16 is found on this turn signal switch.The logic switch object belongs to the family of AS.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 4.5V.The maximal supply voltage (Vsup) should be kept at 5.5V to avoid some unnecessary failures.The turn signal switch operates with 1 outputs.The multiplexer is equipped with 2 inputs.
