SN74AS257NSR Product Details

SN74AS257NSR Overview


Due to the fact that it is provided in the 16-SOIC (0.209, 5.30mm Width), digital switch allows the board to be compacted.Tape & Reel (TR) represents its packaging.digital switch ic uses the method of Surface Mount for mounting.the multiplexers uses an analog IC Multiplexer.By keeping the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.A supply voltage of 4.5V~5.5V 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 74AS series.Among its basic features are 16 terminations.There is a base part number of 74AS257 which can also be used in order to locate the logic switch that are related to this item.In this case, 5V is the voltage supplied to the multiplexer's system.A component pin count of 16 can be found on this turn signal switch.A conductor terminates at GULL WING.In this case, the supply type is Single.The board has 16 pins configured.This unit is mounted in the way of Surface Mount.Among the family of AS the logic switch is a member.The multiplexer ic provides 2 bits.In order to maintain mux switch's normal operation, power is provided to 5V.In order for the turn signal switch to work, there are 1 outputs.The performance of the multiplexers can be reliably maintained at a voltage of 5V.The multiplexer provides 8 inputs.The switches packaging is based on TR.A total of 4 channels are used for transmission in the turn signal switch's circuit.
