DM74AS257M Overview
This is a relatively small item of digital switch that is included in the 16-SOIC (0.154, 3.90mm Width) in order to save space on the board.Tube represents its packaging.For mounting, digital switch ic uses the method Surface Mount.In the multiplexers, the analog IC Multiplexer is used.A temperature of 0°C~70°C will not leave the turn signal swturn signal switchch susceptible to external influences.Using a 4.5V~5.5V supply voltage provides digital controlled switch's superior flexibility for designers.Multiplexers of the 74AS series can be used in a wide range of applications.You can also find related parts by using its logic switch base part number of 74AS257.Single is used as its supply type.This multiplexer ic has 16 pins configured.As you can see, it is mounted in the direction of Surface Mount.The multiplexer ic provides 4 bits.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.This multiplexer has a total of 8 inputs.A signal source has 2 output lines.
