SN74HC257D 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 the manner of Tube.Digital switch ic uses a Surface Mount mounting method.In the multiplexers, the analog IC is indicated by Multiplexer.The operating temperature will not be affected by external factors when turn signal switch is set to -40°C~85°C.When operated with a 2V~6V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.As a member of 74HC series, the multiplexers can be used for a wide range of applications.Its basic configuration includes terminations in the 16 range.The part number for 74HC257 can be used to find its logic switch related parts as well.In multiplexer's system, 5V is the voltage supplied.Currently, this turn signal switch has a total of 16 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.There is a type of supply Single that is employed in this case.A total of 16 pins are configured on this board.The multiplexer ic is mounted in the direction of Surface Mount.The logic switch belongs to the family of HC/UH.The multiplexer ic provides 2 bits.In order to prevent unnecessary failures, it is recommended that the minimal supply voltage (Vsup) be kept at 2V.Vsup (maximum supply voltage) should be kept as 6V to prevent unnecessary failures.The turn signal switch operates with 1 outputs.No external influence consumes 8μA current of multiplexer ic.Supply voltages of 5V can provide reliable performance of the multiplexers.A multiplexer such as this has 8 inputs available.A total of 4 transmission channels are available in the turn signal switch's circuit.
