SN74AHC138DG4 Overview
Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).It is packaged according to the Tube method.For mounting, digital switch ic uses the method Surface Mount.the multiplexers uses IC Decoder/Demultiplexer as the analog IC.By keeping the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.Designers have greater flexibility when digital controlled switch operates at a 2V~5.5V supply voltage.These multiplexers are members of the 74AHC series, which provide extensive application potential.The basic configuration includes 16 terminations.There is a base part number 74AHC138 that can be used to locate signal switch's related components as well.In this case, 3.3V is the voltage supplied to the multiplexer's system.There are 16 component pins in this turn signal switch.As the end of conductors, it uses GULL WING.There is a supply type of Single employed as part of this supply.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 AHC/VHC/H/U/V family.Signal multiplexer consists of 8 bits.Avoid unnecessary failures by keeping the supply voltage (Vsup) at 2V.Vsup (maximum supply voltage) should be kept as 5.5V to prevent unnecessary failures.There is a power supply provided for the mux switch's normal operation of 2/5.5V.This turn signal switch has 8 outputs designed for its operation.The part belongs to the Decoder/Drivers category of signal switches.Not being affected by the external factors, consumes 4μA current of multiplexer ic.In this multiplexer, there is a total of 3 inputs.In mux switch configuration, there are 1 elements.
