74HCT257DB,112 Overview


This is a relatively small item of digital switch that is included in the 16-SSOP (0.209, 5.30mm Width) in order to save space on the board.Tube is the method used for packaging.As far as mounting is concerned, digital switch ic uses Surface Mount.For the analog part of the multiplexers, an IC Multiplexer is used.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -40°C~125°C.Design engineers have more flexibility when digital controlled switch operates at 4.5V~5.5V voltage.In addition to being a member of the 74HCT series, these multiplexers have a wide range of applications.There is a design for terminating 16 as part of its basic configuration.There is a base part number of 74HCT257 which can also be used in order to locate the logic switch that are related to this item.The multiplexer's system is powered by 5V volts.In this turn signal switch, there are 16 component pins.GULL WING is used as the point at which the conductors come to an end as part of this formula.There is a supply type of Single employed as part of this supply.It is configured with 16 pins.The mounting point is Surface Mount.I would like to refer to the logic switch as a member of the HCT family.In order to maintain mux switch's normal operation, power is provided to 5V.The turn signal switch contains 4 outputs designed to operate.The performance of the multiplexers can be reliably maintained at a voltage of 5V.It is provided with 8 inputs.A voltage level can be inserted into the 2 input lines of multiplexers.
