SN74HC138D Overview

This is a relatively small item of digital switch that is included in the 16-SOIC (0.154, 3.90mm Width) in order to save space on the board.The package is packaged in accordance with Tube.The method digital switch ic adopts for mounting is Surface Mount.As the analog part, the circuit uses an analog IC Decoder/Demultiplexer.When the operating temperature is kept at -40°C~85°C, the machine will not be sensturn signal switchive to external influences.With a supply voltage of 2V~6V, designers have greater flexibility of digital controlled switch.The multiplexers from 74HC series can be used for a wide range of applications.It is designed with 16 terminations as part of its basic configuration.There is a base part number of 74HC138 which can also be used in order to locate the logic switch that are related to this item.The multiplexer's system is powered by 5V voltage.There are 16 component pins in this turn signal switch.It employs GULL WING as the point at which conductors come to an end.As a type of supply, Single is employed.There are 16 pins on it.The mounting is in the way of Surface Mount.The logic switch is included into the family of HC/UH.Signal multiplexer provides 8 bits.It is recommended that the minimum supply voltage (Vsup) be kept at 2V to avoid some unnecessary failures.The maximal supply voltage (Vsup) should be kept at 6V to avoid some unnecessary failures.For mux switch's normal operation, power supply 2/6V is provided.The turn signal switch has 8 outputs.The part belongs to the Decoder/Drivers category of signal switches.It consumes 8μA current of multiplexer ic without external influences.Reliable performance of the multiplexers can be achieved when a supply voltage of 5V is provided.There are 3 inputs provided in this multiplexer.During normal operation, the digitalswitch consists of 1 circuits.
