SN74AS138D Overview
As a means of saving space, digital switch is provided in the 16-SOIC (0.154, 3.90mm Width).Tube is the method used for packaging.Digital switch ic uses a Surface Mount mounting method.For the analog part of the multiplexers, an IC Decoder/Demultiplexer is used.As long as the operating temperature is 0°C~70°C, turn signal switch will not be influenced by external factors.Designers have greater flexibility using digital controlled switch when it works with 4.5V~5.5V voltage.The multiplexers can be used for a wide range of applications since they are members of 74AS series.The basic configuration of this system includes 16 terminations.There is a base part number of 74AS138 which can also be used in order to locate the logic switch that are related to this item.In this case, 5V is the voltage supplied to the multiplexer's system.In this turn signal switch, there are 16 component pins.A conductor terminates at GULL WING.There is a type of supply of Single.Currently, it is configured with 16 pins.As you can see, it is mounted in the direction of Surface Mount.The logic switch is included into the family of AS.There are 8 bits signal multiplexer provides.The power supply of 5V is provided for mux switch's normal operation.In order for the turn signal switch to work, there are 8 outputs.In electronic terms, the digital switch ic is classified as part number Decoder/Drivers.If the supply voltage is set to 5V, reliable performance of the multiplexers can be achieved.In this multiplexer, there is a total of 3 inputs.There are 1 elements used for the mux switch configuration.
