SN74LS257BD 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).Tube is the packaging method.In terms of mounting, digital switch ic uses the method of Surface Mount.the multiplexers uses IC Multiplexer as the analog IC.By maintaining the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 4.75V~5.25V, designers are provided with a greater degree of flexibility.The multiplexers from 74LS series can be used for a wide range of applications.There is a design for terminating 16 as part of its basic configuration.In addition, it also has a base part number of 74LS257, which can be used to find related parts.For multiplexer's system, 5V voltage is supplied.There are 16 component pins in this turn signal switch.A conductor terminates at GULL WING.Its supply type is Single, which is used as the source of power.Currently, it is configured with 16 pins.It is mounted in the way of Surface Mount.I would like to refer to the logic switch as a member of the LS family.In the signal multiplexer, there are 2 bits available.For mux switch's normal operation, power supply 5V is provided.As part of the operation of this turn signal switch, there are 1 outputs.Reliable performance of the multiplexers can be achieved when a supply voltage of 5V is provided.The multiplexer is equipped with 8 inputs.The turn signal switch's circuit consists of 4 transmission channels.
