SN74LVC257AQDREP Overview


Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).Tape & Reel (TR) is the method used for packaging.Surface Mount is the mounting method digital switch ic uses.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.In the case of -40°C~125°C, turn signal switch will not be affected by external factors.Using a 2V~3.6V supply voltage provides digital controlled switch's superior flexibility for designers.Several applications are possible for 74LVC series multiplexers.The basic configuration includes 16 terminations.The base part number is 74LVC257, so you can find its logic switch related parts using that number.The multiplexer's system works with 2.7V voltage.This turn signal switch has a total of 16 component pins.GULL WING represents the end of conductors.In this case, the supply type is Single.The board is configured with 16 pins.The multiplexer ic is mounted in the direction of Surface Mount.The logic switch belongs to the family of LVC/LCX/Z.It is recommended that the minimum supply voltage (Vsup) be kept at 2V so that unnecessary failures can be prevented.In order to avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 3.6V.mux switch's normal operation requires the power supply of 3.3V.In order for the turn signal switch to work, there are 4 outputs.The multiplexer provides 8 inputs.According to TAPE AND REEL, the switches is packaged.To accept voltage levels, the multiplexers have2 input lines.
