SN74F257NSR Overview
This is a relatively small item of digital switch that is included in the 16-SOIC (0.209, 5.30mm Width) in order to save space on the board.As a result, it is packaged in a way that is referred to as Tape & Reel (TR).The mounting method digital switch ic uses is Surface Mount.Multiplexer is the analog IC that the multiplexers uses.In the case of 0°C~70°C, turn signal switch will not be affected by external factors.Using a 4.5V~5.5V supply voltage provides digital controlled switch's superior flexibility for designers.In addition to being a member of the 74F series, these multiplexers have a wide range of applications.As parts of its basic configuration, 16 terminations are desgined.There is a base part number 74F257 that can be used to locate signal switch's related components as well.In multiplexer's system, 5V is the voltage supplied.A component pin count of 16 can be found on this turn signal switch.As a result, GULL WING represents the end of the conductors.In this case, Single is employed as the supply type.A total of 16 pins are configured on this board.It is mounted in the way of Surface Mount.The logic switch is a member of the family of F/FAST.In this signal multiplexer, there are 4 bits provided.There are 1 outputs designed to operate the turn signal switch.If the supply voltage is set to 5V, reliable performance of the multiplexers can be achieved.This multiplexer is equipped with 8 inputs and 8 outputs.According to TR, the switches is packaged.As a voltage level input, the multiplexers have 2 lines.
