CD74HCT257M Overview
This is a relatively small item of digital switch that is included in the 16-SOIC (0.154, 3.90mm Width) in order to save space on the board.Tube is the packaging method.digital switch ic uses the method of Surface Mount for mounting.the multiplexers uses IC Multiplexer as the analog IC.When the operating temperature is kept at -55°C~125°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.The multiplexers from 74HCT series can be used for a wide range of applications.It is designed with 16 terminations as part of its basic configuration.To find signal switch's related components, a base part number of 74HCT257 may also be used.The multiplexer's system works with 5V voltage.Signal switch has 16 component pins.As the end of conductors, it uses GULL WING.Single is used 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 family of HCT.There are 2 bits in signal multiplexer.In order to avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.mux switch's normal operation requires the power supply of 5V.The turn signal switch operates with 1 outputs.In this multiplexer, there is a total of 8 inputs.This turn signal switch's circuit uses 4 transmission channels.
