DM74AS157M Overview
In order to save board space, digital switch is located in the 16-SOIC (0.154, 3.90mm Width).Tube is the packaging method.Digital switch ic uses a Surface Mount mounting method.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.Designers have greater flexibility when digital controlled switch operates at a 4.5V~5.5V supply voltage.In addition to being a member of the 74AS series, these multiplexers have a wide range of applications.There is a design for terminating 16 as part of its basic configuration.The voltage supplied for multiplexer's system is 5V.multiplexer's systemGULL WING is used as the point at which the conductors come to an end as part of this formula.The logic switch is included into the family of AS.The minimal supply voltage (Vsup) should be kept at 4.5V to avoid some unnecessary failures.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 is equipped with 2 inputs and 2 outputs.
