SN74LS253DR 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).Tape & Reel (TR) is the packaging method.In terms of mounting, digital switch ic uses the method of Surface Mount.the multiplexers uses an analog IC Multiplexer.As long as the operating temperature is 0°C~70°C, turn signal switch will not be influenced by external factors.The turn signal switch is designed for use with a 4.75V~5.25V supply voltage, which gives it a lot of flexibility.Multiplexers in the 74LS series are suitable for a wide range of applications.As parts of its basic configuration, 16 terminations are desgined.The base part number is 74LS253, so you can find its logic switch related parts using that number.In multiplexer's system, 5V is the voltage supplied.Currently, this turn signal switch has a total 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.In this case, the supply type is Single.A total of 16 pins are configured on this board.The mounting point is Surface Mount.In the LS family, the logic switch is included.In this signal multiplexer, there are 4 bits that are provided.For mux switch's normal operation, power supply 5V is provided.There are 1 outputs designed to operate the turn signal switch.It is possible to achieve reliable performance of the multiplexers with a voltage supply of 5V.It is provided with 8 inputs.Currently, the switches is packaged in accordance with the TR method.This turn signal switch's circuit uses 2 transmission channels.
