SN74HC139NSR Overview

This is a relatively small item of digital switch that is included in the 16-SOIC (0.209, 5.30mm Width) in order to save space on the board.As a result, it is packaged in a way that is referred to as Tape & Reel (TR).digital switch ic uses the method of Surface Mount for mounting.As the analog part, the circuit uses an analog IC Decoder/Demultiplexer.The operating temperature of -40°C~85°C will not be susceptible to external factors.When digital controlled switch operates at 2V~6V, designers have superior flexibility.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 74HC139 that can be used to locate signal switch's related components as well.The multiplexer's system is powered by 5V volts.Currently, this turn signal switch has a total of 16 component pins.GULL WING represents the end of conductors.This supply type employs Single.There are 16 pins on it.The multiplexer ic is mounted in the direction of Surface Mount.The logic switch is included into the family of HC/UH.There are 4 bits in signal multiplexer.To avoid unnecessary failures, keep the supply voltage at 2V (Vsup).It is advisable that the maximal supply voltage (Vsup) remains at 6V to avoid some unnecessary failures.There are 4 outputs designed for the operation of the turn signal switch.The digital switch ic is an electronic part classified into Decoder/Drivers.It consumes 80μA current of multiplexer ic without external influences.Using a supply voltage of 5V can result in reliable performance of the multiplexers.The switches is packaged according to the way of TR.In the mux switch configuration, there are 2 elements.
