SN74HC138DT Overview
For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).The package is packaged in accordance with Tape & Reel (TR).In terms of mounting, digital switch ic uses the method of Surface Mount.The analog IC in the multiplexers is identified as Decoder/Demultiplexer.In the case of -40°C~85°C, turn signal switch will not be affected by external factors.Using a 2V~6V supply voltage 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.There are 16 terminations included in its basic configuration.The base part number is 74HC138, which can also be used to find its logic switch related parts.The multiplexer's system is powered by 5V volts.In this turn signal switch, there are 16 components that can be connected to each pin.It employs GULL WING as the point at which conductors come to an end.There is a type of supply Single that is employed in this case.With 16 pins, it is configured.The multiplexer ic is mounted in the direction of Surface Mount.Among the family of HC/UH the logic switch is a member.There are 8 bits in signal multiplexer.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 2V.Keeping Vsup at 6V will prevent some unnecessary failures.Normally, 2/6V is powered by a battery.For the turn signal switch's operation, there are 8 outputs.Decoder/Drivers is a category for the digital switch ics.In the absence of external influences, it consumes 8μA current of multiplexer ic.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.The multiplexer provides 3 inputs.The switches packaging is based on TR.A configuration element for the mux switch consists of 1 elements.
