SN74HC257PWT Overview
For the purpose of saving board space, digital switch is included in the 16-TSSOP (0.173, 4.40mm Width).As a result, it is packaged in the way of Tape & Reel (TR).Digital switch ic uses a Surface Mount mounting method.The analog IC in the multiplexers is identified as Multiplexer.As long as the operating temperature is -40°C~85°C, turn signal switch will not be influenced by external factors.Designers have greater flexibility when digital controlled switch operates at a 2V~6V supply voltage.With the 74HC series, the multiplexers are suitable for a diverse range of applications.The basic configuration of this system includes 16 terminations.In multiplexer's system, 5V is the voltage supplied.A conductor terminates at GULL WING.The logic switch object belongs to the family of HC/UH.Keeping Vsup at 2V will prevent some unwanted failures.It is advisable that the maximal supply voltage (Vsup) remains at 6V to avoid some unnecessary failures.For the turn signal switch's operation, there are 1 outputs.The multiplexer is equipped with 2 inputs.
