DM74AS257N Overview

Digital switch is provided in the 16-DIP (0.300, 7.62mm) for the purpose of saving board space.It is packaged in the way of Tube.The method digital switch ic adopts for mounting is Through Hole.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.It provides digital controlled switch's superior flexibility for designers to use when it operates with a supply voltage of 4.5V~5.5V.provides digital controlled switch's digital controlled switch'sAs a member of 74AS series, the multiplexers can be used for a wide range of applications.Its logic switch base part number is 74AS257 which can also be used to find its logic switch related parts.Single is employed as its supply type.It is configured with 16 pins.It is mounted in the way of Through Hole.There are 4 bits signal multiplexer provides.There are 4 outputs designed for the operation of the turn signal switch.Not being affected by the external factors, consumes 19.7mA current of multiplexer ic.Reliable performance of the multiplexers can be achieved when a supply voltage of 5V is provided.There are 8 inputs provided in this multiplexer.The multiplexers have 1 input lines used to accept voltage levels.There are 2 output lines designed to serve as the source of the signal.It is acceptable for this signal switch to operate at the maximal temperature of 70°C.The minimal operating temperature of the multiplexer should be maintained at 0°C.The signal switches is specified to operate at the maximum supply voltage of 5.5V in compliance with the applicable device specification.The digital swith is specified to operate at the minimum supply voltage of 4.5V in compliance with the applicable device specification.4 circuits are formed for the normal operation of the digitalswitch.
