SN74LS257BDR Overview
For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).Tape & Reel (TR) is the method used for packaging.Mounting is performed using Surface Mount.the multiplexers uses an analog IC Multiplexer.By maintaining the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.Designers have greater flexibility when digital controlled switch operates at a 4.75V~5.25V supply voltage.These multiplexers are members of the 74LS series, which provide extensive application potential.This configuration includes 16 terminations as part of its basic functionality.In addition, it also has a base part number of 74LS257, which can be used to find related parts.The multiplexer's system is powered by 5V voltage.This turn signal switch has 16 component pins.It employs GULL WING as the point at which conductors come to an end.Single is employed as its supply type.This multiplexer ic is configured with 16 pins.The multiplexer ic is mounted in the direction of Surface Mount.The LS family includes the logic switch.Signal multiplexer consists of 2 bits.A power supply is provided for mux switch's normal operation of 5V.In order for the turn signal switch to work, there are 1 outputs.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.The signal switching is packaged by TR. This turn signal switch's circuit uses 4 transmission channels.
