SN74AHC138DBR Overview


The reason it is provided is that the board space can be saved by placing digital switch in the 16-SSOP (0.209, 5.30mm Width).As a result, it is packaged in a way that is referred to as Cut Tape (CT).Surface Mount is the mounting method digital switch ic uses.A digital IC Decoder/Demultiplexer is used as the analog component of the multiplexers.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at -40°C~85°C.Designers have greater flexibility when digital controlled switch operates at a 2V~5.5V supply voltage.The multiplexers from 74AHC series can be used for a wide range of applications.The basic configuration of this system includes 16 terminations.There is a base part number of 74AHC138 which can also be used in order to locate the logic switch that are related to this item.In this case, 3.3V is the voltage supplied to the multiplexer's system.Signal switch has 16 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.This supply type employs Single.It is configured with 16 pins.It is mounted in the way of Surface Mount.The logic switch is included into the family of AHC/VHC/H/U/V.The multiplexer ic provides 8 bits.It is recommended that the minimum supply voltage (Vsup) be kept at 2V so that unnecessary failures can be prevented.The maximal supply voltage (Vsup) should be kept at 5.5V to avoid some unnecessary failures.Normally, 2/5.5V is powered by a battery.In order for the turn signal switch to work, there are 8 outputs.In electronic terms, the digital switch ic is classified as part number Decoder/Drivers.Without external influences, it consumes 4μA current of multiplexer ic.In this multiplexer, there is a total of 3 inputs.A TR packaging method is used in the switches.To operate the digitalswitch normally, 1 circuits are formed.
