SN74AHC139D Overview


In order to conserve board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).Tube is the packaging method.As far as mounting is concerned, digital switch ic uses Surface Mount.As the analog part, the circuit uses an analog IC Decoder/Demultiplexer.If the operating temperature is maintained at -40°C~125°C, turn signal switch will not be susceptible to external factors.Designers have greater flexibility when digital controlled switch operates at a 2V~5.5V supply voltage.Since they are members of the 74AHC series, they can be used in a wide variety of applications.As parts of its basic configuration, 16 terminations are desgined.The base part number is 74AHC139, so you can find its logic switch related parts using that number.In this case, 3.3V is the voltage supplied to the multiplexer's system.This turn signal switch contains 16 component pins.As a result, GULL WING represents the end of the conductors.There is a type of supply Single that is employed in this case.There are 16 pins on it.The multiplexer ic is mounted in the direction of Surface Mount.I would like to refer to the logic switch as a member of the AHC/VHC/H/U/V family.In this signal multiplexer, there are 4 bits that are provided.To avoid unnecessary failures, keep the supply voltage at 2V (Vsup).Avoid unnecessary failures by keeping Vsup at 5.5V.There are 4 outputs designed for the operation of the turn signal switch.In electronic terms, the digital switch ic is classified as part number Decoder/Drivers.Despite not interacting with external factors, it consumes 4μA current of multiplexer ic.In order for the digitalswitch to function normally, it has 2 circuits.
