                                                74AHCT138BQ,115 Overview
As a means of saving space, digital switch is provided in the 16-VFQFN Exposed Pad.The package is packaged in the manner of Tape & Reel (TR).The mounting method digital switch ic uses is Surface Mount.In the multiplexers, the analog IC is indicated by Decoder/Demultiplexer.If the operating temperature is maintained at -40°C~125°C, turn signal switch will not be susceptible to external factors.A supply voltage of 4.5V~5.5V provides digital controlled switch's superior flexibility for designers.Multiplexers of the 74AHCT series can be used in a wide range of applications.There are 16 terminations included in its basic configuration.There is a base part number 74AHCT138 that can be used to locate signal switch's related components as well.The multiplexer's system is supplied with a voltage of 5V.This turn signal switch consists of 16 component pins.As a type of supply, Single is employed.This multiplexer ic is configured with 16 pins.The mounting point is Surface Mount.I would like to refer to the logic switch as a member of the AHCT/VHCT/VT family.Without external influences, it consumes  4μA current of multiplexer ic.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.For the purpose of accepting voltage levels, the multiplexers have 3 input lines.A signal source is provided by 8 output lines.
