SN74F257DRG4 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) represents its packaging.The mounting method digital switch ic uses is Surface Mount.The multiplexers uses an analog IC Multiplexer as the analog part of the circuit.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at 0°C~70°C.Designers have greater flexibility when digital controlled switch operates at a 4.5V~5.5V supply voltage.In addition to being a member of the 74F series, these multiplexers have a wide range of applications.There is a design for terminating 16 as part of its basic configuration.The base part number is 74F257, which can also be used to find its logic switch related parts.The multiplexer's system is supplied with a voltage of 5V.A component pin count of 16 is found on this turn signal switch.GULL WING is used as the point at which the conductors come to an end as part of this formula.Single is employed as its supply type.The board is configured with 16 pins.The mount is in Surface Mount.The logic switch is included into the family of F/FAST.There are 4 bits in signal multiplexer.There is a power supply provided for the mux switch's normal operation of 5V.The turn signal switch has 1 outputs.When a supply voltage of 5V is used, reliable performance of the multiplexers can be achieved.The multiplexer is equipped with 8 inputs.A TR packaging method is used in the switches.It is possible to accept voltage levels through 2 input lines of multiplexers.
