SN74HCT157DR Overview


This is a relatively small item of digital switch that is included in the 16-SOIC (0.154, 3.90mm Width) in order to save space on the board.Tape & Reel (TR) represents its packaging.For mounting, digital switch ic uses the method Surface Mount.In the multiplexers, the analog IC is indicated by Multiplexer.As long as the operating temperature is -40°C~85°C, turn signal switch will not be influenced by external factors.When digital controlled switch operates at 4.5V~5.5V, designers are provided with a greater degree of flexibility.Several applications are possible for 74HCT series multiplexers.There is a design for terminating 16 as part of its basic configuration.The base part number is 74HCT157, 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.GULL WING represents the end of conductors.In this case, the supply type is Single.The board has 16 pins configured.The mounting is in the way of Surface Mount.The HCT family includes the logic switch.As a result, signal multiplexer provides a total of 2 bits.For mux switch's normal operation, power supply 5V is provided.There are 1 outputs designed to operate the turn signal switch.Reliable performance of the multiplexers can be achieved when a supply voltage of 5V is provided.This multiplexer is equipped with 8 inputs and 8 outputs.A TR packaging method is used in the switches.The turn signal switch's circuit consists of 4 channels that are being used for transmission in the circuit.
