SN74AHC138DR 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).As far as mounting is concerned, digital switch ic uses Surface Mount.For the analog part of the multiplexers, an IC Decoder/Demultiplexer is used.The operating temperature of -40°C~85°C will not be susceptible to external factors.When digital controlled switch operates at 2V~5.5V, designers are provided with a greater degree of flexibility.The multiplexers can be used for a wide range of applications since they are members of 74AHC series.Among its basic features are 16 terminations.As its base part number is 74AHC138, logic switch can also be used to find its related parts.The multiplexer's system is powered by 3.3V voltage.This turn signal switch has 16 component pins.At the end of a conductor, it uses GULL WING as the point where the conductor ends.This supply type employs Single.A total of 16 pins are configured on this board.The mounting point is Surface Mount.The logic switch is a member of the family of AHC/VHC/H/U/V.The multiplexer ic provides 8 bits.Keeping Vsup at 2V will prevent some unwanted failures.Keeping Vsup at 5.5V will prevent some unnecessary failures.It is provided that 2/5.5V has a power supply in order to function normally.There are 8 outputs designed to operate the turn signal switch.I would classify the digital switch ic as an electronic part belonging to the Decoder/Drivers category.No external influence consumes 4μA current of multiplexer ic.The multiplexer is equipped with 3 inputs.The switches is packaged according to the way of TR.During normal operation, the digitalswitch consists of 1 circuits.
