MC74AC257NG Overview
Digital switch is provided in the 16-DIP (0.300, 7.62mm) for the purpose of saving board space.Tube is the method used for packaging.The mounting method digital switch ic uses is Through Hole.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.As long as the operating temperature is -40°C~85°C, turn signal switch will not be influenced by external factors.When digital controlled switch operates at 2V~6V, designers have superior flexibility.The multiplexers can be used for a wide range of applications since they are members of 74AC series.This configuration includes 16 terminations as part of its basic functionality.The multiplexer's system works with 5V voltage.Currently, this turn signal switch has a total of 16 component pins.The logic switch object belongs to the family of AC.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 2V.The maximal supply voltage (Vsup) should be kept at 6V to avoid some unnecessary failures.There are 1 outputs designed for the operation of the turn signal switch.The multiplexer provides 2 inputs.
