CD74AC257E Overview


Digital switch is provided in the 16-DIP (0.300, 7.62mm) for the purpose of saving board space.The package is packaged in accordance with Tube.The method digital switch ic adopts for mounting is Through Hole.The analog IC in the multiplexers is identified as Multiplexer.As long as the operating temperature is -55°C~125°C, turn signal switch will not be influenced by external factors.When digital controlled switch operates at 1.5V~5.5V, designers are provided with a greater degree of flexibility.The multiplexers from 74AC series can be used for a wide range of applications.Among its basic features are 16 terminations.The multiplexer's system is powered by 5V volts.The logic switch is included into the family of AC.Keeping Vsup at 5.5V will prevent some unnecessary failures.In order for the turn signal switch to work, there are 1 outputs.It has 2 inputs.
