SN74HCT257DT Overview
As a means of saving space, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).As a result, it is packaged in the way of Tape & Reel (TR).For mounting, digital switch ic uses the method Surface Mount.The analog IC used in the multiplexers can be referred to as Multiplexer.When the operating temperature is kept at -40°C~85°C, the machine will not be sensturn signal switchive to external influences.With a supply voltage of 4.5V~5.5V, designers have greater flexibility of digital controlled switch.Multiplexers from the 74HCT series can be used in a wide range of applications.It is designed with 16 terminations as part of its basic configuration.The base part number is 74HCT257, so you can find its logic switch related parts using that number.In multiplexer's system, 5V is the voltage supplied.This turn signal switch has a total of 16 component pins.GULL WING represents the end of conductors.In this case, the supply type is Single.A configuration of 16 pins is used.As you can see, it is mounted in the direction of Surface Mount.The logic switch belongs to the family of HCT.There are 2 bits in signal multiplexer.The maximal supply voltage (Vsup) should be kept at 5.5V to avoid some unnecessary failures.In order to maintain mux switch's normal operation, power is provided to 5V.As part of the operation of this turn signal switch, there are 1 outputs.In this multiplexer, there is a total of 8 inputs.The switches is packaged according to the way of TAPE AND REEL.A total of 4 channels are used for transmission in the turn signal switch's circuit.There is an output current of 6mA that allows for greater switches' flexibility.
