SN74AS257N Overview
For the purpose of saving board space, digital switch is included in the 16-DIP (0.300, 7.62mm).Tube is the method used for packaging.Through Hole is the mounting method digital switch ic uses.As the analog part, the circuit uses an analog IC Multiplexer.When the operating temperature is kept at 0°C~70°C, the machine will not be sensturn signal switchive to external influences.Design engineers have more flexibility when digital controlled switch operates at 4.5V~5.5V voltage.Multiplexers of the 74AS series can be used in a wide range of applications.This configuration includes 16 terminations as part of its basic functionality.In addition, it also has a base part number of 74AS257, which can be used to find related parts.In this case, 5V is the voltage supplied to the multiplexer's system.This turn signal switch contains 16 component pins.In this case, Single is employed as the supply type.Currently, it is configured with 16 pins.It is positioned in the direction of Through Hole.There is a family of AS members.As a result, signal multiplexer provides 2 bits.During mux switch's normal operation, 5V is provided with a power supply.The turn signal switch contains 1 outputs designed to operate.Reliable performance of the multiplexers can be achieved when a supply voltage of 5V is provided.There are 8 inputs provided in this multiplexer.Transmission is carried out over 4 channels in the turn signal switch's circuit.
