SN74ALS257ADG4 Overview
Due to the fact that it is provided in the 16-SOIC (0.154, 3.90mm Width), digital switch allows the board to be compacted.The package is in the form of Tube.Digital switch ic uses a Surface Mount mounting method.the multiplexers uses IC Multiplexer as the analog IC.A temperature of 0°C~70°C will not leave the turn signal swturn signal switchch susceptible to external influences.Designers have greater flexibility using digital controlled switch when it works with 4.5V~5.5V voltage.With the 74ALS series, the multiplexers are suitable for a diverse range of applications.As parts of its basic configuration, 16 terminations are desgined.There is a base part number of 74ALS257 which can also be used in order to locate the logic switch that are related to this item.The voltage supplied for multiplexer's system is 5V.multiplexer's systemIn this turn signal switch, there are 16 component pins.Conductors terminate at GULL WING in this design.This supply type employs Single.This multiplexer ic is configured with 16 pins.It is mounted in the way of Surface Mount.The logic switch belongs to the family of ALS.In this signal multiplexer, there are 2 bits that are provided.In order to avoid some unnecessary failures, you should maintain a maximum supply voltage (Vsup) of 5.5V.There is a power supply provided for the mux switch's normal operation of 5V.The turn signal switch contains 1 outputs designed to operate.It has 8 inputs.The turn signal switch's circuit consists of 4 transmission channels.
