SN74LS257BD Overview


Providing this information in the 16-SOIC (0.154, 3.90mm Width) enables digital switch board space to be saved.It is packaged according to the Tube method.Digital switch ic adheres to a mounting method of Surface Mount.Multiplexer is the analog IC that the multiplexers uses.A temperature of 0°C~70°C will not leave the turn signal swturn signal switchch susceptible to external influences.Designers have greater flexibility when digital controlled switch operates at a 4.75V~5.25V supply voltage.Multiplexers in the 74LS series are suitable for a wide range of applications.It is designed with 16 terminations as part of its basic configuration.For multiplexer's system, 5V voltage is supplied.In this turn signal switch, there are 16 components that can be connected to each pin.As a result, GULL WING represents the end of the conductors.In the LS family, the logic switch is included.Keeping the minimum supply voltage (Vsup) at 4.75V prevents some unnecessary failures.It is advisable to keep the maximum supply voltage (Vsup) at 5.25V so as to avoid some unnecessary failures.The turn signal switch has 1 outputs.The multiplexer is equipped with 2 inputs.
