MC74ACT257D Overview
Providing this information in the 16-SOIC (0.154, 3.90mm Width) enables digital switch board space to be saved.The package is packaged in the manner of Tube.In terms of mounting, digital switch ic uses the method of Surface Mount.As the analog part, the circuit uses an analog IC Multiplexer.If the operating temperature is maintained at -40°C~85°C, turn signal switch will not be susceptible to external factors.Using a 4.5V~5.5V supply voltage provides digital controlled switch's superior flexibility for designers.Multiplexers in the 74ACT series are suitable for a wide range of applications.Among its basic configurations are 16 terminations.In this case, 5V is the voltage supplied to the multiplexer's system.There are 16 component pins in this turn signal switch.As the end of conductors, it uses GULL WING.The logic switch belongs to the family of ACT.Keeping Vsup at 4.5V will prevent some unwanted failures.It is advisable to keep the maximum supply voltage (Vsup) at 5.5V in order to prevent some unnecessary failures.This turn signal switch has 1 outputs designed for its operation.It is provided with 2 inputs.
