DM74ALS257MX Overview
Providing this information in the 16-SOIC (0.154, 3.90mm Width) enables digital switch board space to be saved.Tape & Reel (TR) is the method used for packaging.Digital switch ic adheres to a mounting method of Surface Mount.the multiplexers uses an analog IC Multiplexer.In the case of 0°C~70°C, turn signal switch will not be affected by external factors.A supply voltage of 4.5V~5.5V provides digital controlled switch's superior flexibility for designers.Multiplexers of the 74ALS series can be used in a wide range of applications.There is a design for terminating 16 as part of its basic configuration.In this case, 5V is the voltage supplied to the multiplexer's system.In this turn signal switch, there are 16 components that can be connected to each pin.GULL WING is used as the point at which the conductors come to an end as part of this formula.I would like to refer to the logic switch as a member of the ALS family.Vsup should be kept at 4.5V to prevent some unnecessary failures.Vsup (maximum supply voltage) should be kept as 5.5V to prevent unnecessary failures.In order for the turn signal switch to work, there are 1 outputs.This multiplexer is equipped with 2 inputs and 2 outputs.
