SN74F257DR Overview


The reason it is provided is that the board space can be saved by placing digital switch in the 16-SOIC (0.154, 3.90mm Width).It is packaged in the way of Tape & Reel (TR).Digital switch ic adheres to a mounting method of Surface Mount.Multiplexer is the analog IC that the multiplexers uses.By keeping the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.When operated with a 4.5V~5.5V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.These multiplexers are members of the 74F series, which provide extensive application potential.It is designed with 16 terminations as part of its basic configuration.The base part number is 74F257, which is also useful when looking up signal switch's related components.In this case, 5V is the voltage supplied to the multiplexer's system.A component pin count of 16 is found on this turn signal switch.A conductor terminates at GULL WING.In this case, Single is employed as the supply type.It 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.In this signal multiplexer, there are 4 bits that are provided.mux switch's normal operation requires the power supply of 5V.The turn signal switch contains 1 outputs designed to operate.No external influence consumes 15mA current of multiplexer ic.If the supply voltage is 5V, reliable performance of the multiplexers can be achieved.The multiplexer provides 8 inputs.The switches package is packaged in accordance with the TR method.Voltage levels are accepted through 2 input lines of multiplexers.4 circuits are formed for the normal operation of the digitalswitch.
