DM74ALS257M Overview


The reason it is provided is that the board space can be saved by placing digital switch in the 16-SOIC (0.154, 3.90mm Width).The package is packaged in accordance with Tube.In terms of mounting, digital switch ic uses the method of Surface Mount.the multiplexers uses an analog IC Multiplexer.The operating temperature of 0°C~70°C will not be susceptible to external factors.Designers have greater flexibility when digital controlled switch operates at a 4.5V~5.5V supply voltage.With the 74ALS series, the multiplexers are suitable for a diverse range of applications.Among its basic features are 16 terminations.For multiplexer's system, a voltage of 5V is supplied.This turn signal switch has 16 component pins.GULL WING represents the end of conductors.The logic switch is a member of the family of ALS.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 4.5V.It is advisable to keep the maximum supply voltage (Vsup) at 5.5V in order to prevent some unnecessary failures.The turn signal switch has 1 outputs.This multiplexer provides 2 inputs.
