SN74AHC139DR Overview
In order to save board space, digital switch is located in the 16-SOIC (0.154, 3.90mm Width).The package is packaged in the manner of Tape & Reel (TR).For mounting, digital switch ic uses the method Surface Mount.the multiplexers uses an analog IC Decoder/Demultiplexer.The operating temperature will not be affected by external factors when turn signal switch is set to -40°C~125°C.A supply voltage of 2V~5.5V provides digital controlled switch's superior flexibility for designers.In addition to being a member of the 74AHC series, these multiplexers have a wide range of applications.Among its basic features are 16 terminations.You can also find related parts by using its logic switch base part number of 74AHC139.In multiplexer's system, 3.3V is the voltage supplied.There are 16 component pins in this turn signal switch.As a result, GULL WING represents the end of the conductors.This supply type employs Single.A total of 16 pins are configured on this board.Multiplexer ics are mounted in the direction of Surface Mount.The logic switch object belongs to the family of AHC/VHC/H/U/V.The multiplexer ic provides 4 bits.Keeping Vsup at 2V will prevent some unwanted failures.In order to avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 5.5V.The turn signal switch operates with 4 outputs.I would classify the digital switch ic as an electronic part belonging to the Decoder/Drivers category.Without any external influences, it consumes 4μA current of multiplexer ic at all times.The switches package is packaged in a way which is consistent with TR.This mux switch configuration has 2 elements.
