SN74LVC257ADR 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 accordance with Tape & Reel (TR).In terms of mounting, digital switch ic uses the Surface Mount method .Multiplexer is the analog IC that the multiplexers uses.By keeping the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 1.65V~3.6V, designers are provided with a greater degree of flexibility.Multiplexers from the 74LVC series can be used in a wide range of applications.The basic configuration includes 16 terminations.As its base part number is 74LVC257, logic switch can also be used to find its related parts.The turn signal switch is supplied with a voltage of 3.3V volts.This turn signal switch has 16 component pins.GULL WING represents the end of conductors.There is a type of supply Single that is employed in this case.This multiplexer ic has 16 pins configured.This unit is mounted in the way of Surface Mount.The logic switch is included into the family of LVC/LCX/Z.In the signal multiplexer, there are 2 bits available.In order to avoid some unnecessary failures, you should maintain a maximum supply voltage (Vsup) of 3.6V.There is a power supply provided for the mux switch's normal operation of 3.3V.The turn signal switch has 1 outputs.The multiplexer is equipped with 8 inputs.The switches package is packaged in a way which is consistent with TR.This turn signal switch's circuit uses 4 transmission channels.
