MC74AC257N Overview
As a means of saving space, digital switch is provided in the 16-DIP (0.300, 7.62mm).Tube represents its packaging.digital switch ic uses the method of Through Hole for mounting.the multiplexers uses an analog IC Multiplexer.When the operating temperature is kept at -40°C~85°C, the machine will not be sensturn signal switchive to external influences.Using a 2V~6V supply voltage provides digital controlled switch's superior flexibility for designers.In addition to being a member of the 74AC series, these multiplexers have a wide range of applications.As parts of its basic configuration, 16 terminations are desgined.The multiplexer's system works with 5V voltage.A component pin count of 16 can be found on this turn signal switch.Among the family of AC the logic switch is a member.The minimal supply voltage (Vsup) should be kept at 2V to avoid some unnecessary failures.Keeping Vsup at 6V will prevent some unnecessary failures.There are 1 outputs designed for the operation of the turn signal switch.It is provided with 2 inputs.
