SN74LS257BNSR 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.In this case, it is packaged as Tape & Reel (TR).Surface Mount is the mounting method digital switch ic uses.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.With a supply voltage of 4.75V~5.25V, designers have greater flexibility of digital controlled switch.In addition to being a member of the 74LS 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 74LS257 that can be used to locate signal switch's related components as well.The multiplexer's system is powered by 5V volts.This turn signal switch consists of 16 component pins.Using the point GULL WING as an end point of conductors, it is used to determine the terminus of a conductor.Single is employed as its supply type.This multiplexer ic is configured with 16 pins.Surface Mount is the way it is mounted.The logic switch object belongs to the family of LS.Signal multiplexer contains 2 bits.During mux switch's normal operation, 5V is provided with a power supply.There are 1 outputs designed to operate the turn signal switch.When a supply voltage of 5V is used, reliable performance of the multiplexers can be achieved.This multiplexer has 8 inputs.The switches package is packaged in accordance with the TR method.For transmission, there are 4 channels in the turn signal switch's circuit.
