MC74ACT257NG Overview
Digital switch is provided in the 16-DIP (0.300, 7.62mm) for the purpose of saving board space.The package is in the form of Tube.In terms of mounting, digital switch ic uses the Through Hole method .the multiplexers uses an analog IC Multiplexer.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 4.5V~5.5V, designers have superior flexibility.Since they are members of the 74ACT series, they can be used in a wide variety of applications.There are 16 terminations included in its basic configuration.The voltage supplied for multiplexer's system is 5V.multiplexer's systemIn this turn signal switch, there are 16 components that can be connected to each pin.The logic switch is a member of the ACT family.The minimal supply voltage (Vsup) should be kept at 4.5V to avoid some unnecessary failures.Avoid unnecessary failures by keeping Vsup at 5.5V.There are 1 outputs designed for the operation of the turn signal switch.It has 2 inputs.
