SN74HC257DG4 Overview
For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).It is packaged in the way of Tube.The mounting method digital switch ic uses is Surface Mount.The analog IC in the multiplexers is identified as Multiplexer.If the operating temperature is maintained at -40°C~85°C, turn signal switch will not be susceptible to external factors.A supply voltage of 2V~6V provides digital controlled switch's superior flexibility for designers.The multiplexers from 74HC series can be used for a wide range of applications.Among its basic features are 16 terminations.The base part number is 74HC257, which is also useful when looking up signal switch's related components.In multiplexer's system, 5V is the voltage supplied.This turn signal switch contains 16 component pins.A conductor terminates at GULL WING.Single is employed as its supply type.A total of 16 pins are configured on this board.As you can see, it is mounted in the direction of Surface Mount.The logic switch is a member of the HC/UH family.Signal multiplexer consists of 2 bits.It is recommended that the minimum supply voltage (Vsup) be kept at 2V to avoid some unnecessary failures.It is advisable that the maximal supply voltage (Vsup) remains at 6V to avoid some unnecessary failures.This turn signal switch has 1 outputs designed for its operation.A multiplexer such as this has 8 inputs available.For transmission, there are 4 channels in the turn signal switch's circuit.
