SN74F257D Overview


Due to the lack of space on the board, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).The package is packaged in the manner of Tube.In terms of mounting, digital switch ic uses the method of Surface Mount.The analog IC used in the multiplexers can be referred to as Multiplexer.The operating temperature of 0°C~70°C will not be susceptible to external factors.The turn signal switch is designed for use with a 4.5V~5.5V supply voltage, which gives it a lot of flexibility.As a member of 74F series, the multiplexers can be used for a wide range of applications.The basic configuration of this system includes 16 terminations.You can also find related parts by using its logic switch base part number of 74F257.The multiplexer's system is powered by 5V volts.A component pin count of 16 can be found on this turn signal switch.GULL WING represents the end of conductors.There is a supply type of Single employed as part of this supply.The board is configured with 16 pins.The mounting is in the way of Surface Mount.The logic switch is a member of the F/FAST family.There are 4 bits in signal multiplexer.A power supply is provided for mux switch's normal operation of 5V.This turn signal switch has 1 outputs designed for its operation.Without the influence of external factors, it consumes 15mA current of multiplexer ic.With a supply voltage of 5V, reliable performance of the multiplexers can be achieved.This multiplexer is equipped with 8 inputs and 8 outputs.In order to accept voltage levels, the multiplexers have input lines 2 on the board.In order for the digitalswitch to function normally, it has 4 circuits.
