SN74ALS138AD 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).As a result, it is packaged in the way of Tube.For mounting, digital switch ic uses the method Surface Mount.The analog IC used in the multiplexers can be referred to as Decoder/Demultiplexer.Turn signal switch will not be susceptible to the external factors when the operating temperature is kept at 0°C~70°C.Designers have greater flexibility using digital controlled switch when it works with 4.5V~5.5V voltage.With the 74ALS series, the multiplexers are suitable for a diverse range of applications.There is a design for terminating 16 as part of its basic configuration.The base part number is 74ALS138, which is also useful when looking up signal switch's related components.The multiplexer's system is powered by 5V volts.A component pin count of 16 is found on this turn signal switch.As the end of conductors, it uses GULL WING.As a type of supply, Single is employed.The board is configured with 16 pins.The mounting is in the way of Surface Mount.The logic switch is a member of the ALS family.As a result, signal multiplexer provides 8 bits.In order for 5V to operate normally, a power supply is provided.There are 8 outputs designed for the operation of the turn signal switch.Decoder/Drivers is a category for the digital switch ics.Using a supply voltage of 5V can result in reliable performance of the multiplexers.It is provided with 3 inputs.50mA provides a high degree of switches' flexibility.1 circuits are formed for the normal operation of the digitalswitch.
