M74HC139B1R Overview
This is a relatively small item of digital switch that is included in the 16-DIP (0.300, 7.62mm) in order to save space on the board.In this case, it is packaged as Tube.The method digital switch ic adopts for mounting is Through Hole.A digital IC Decoder/Demultiplexer is used as the analog component of the multiplexers.A temperature of -55°C~125°C will not leave the turn signal swturn signal switchch susceptible to external influences.When operated with a 2V~6V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.The multiplexers can be used for a wide range of applications since they are members of 74HC series.Its basic configuration includes terminations in the 16 range.The base part number is M74HC139, which can also be used to find its logic switch related parts.In multiplexer's system, 4.5V is the voltage supplied.In this turn signal switch, there are 16 components that can be connected to each pin.Its supply type is Single, which is used as the source of power.Currently, it is configured with a 16 pin configuration.The mounting is in the way of Through Hole.The logic switch object belongs to the family of HC/UH.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 2V.It is advisable that the maximal supply voltage (Vsup) remains at 6V to avoid some unnecessary failures.As a result, the turn signal switch consists of 4 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.The configuration of the mux switch contains 2 elements.
