For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).Tape & Reel (TR) represents its packaging.The mounting method digital switch ic uses is Surface Mount.As the analog part, the circuit uses an analog IC Decoder.The operating temperature of 0°C~70°C will not be susceptible to external factors.When digital controlled switch operates at 4.75V~5.25V, designers have superior flexibility.The multiplexers from 74LS series can be used for a wide range of applications.As part of its basic configuration, 16 terminations are designed as a part of it.In addition, it also has a base part number of 74LS145, which can be used to find related parts.The turn signal switch is supplied with a voltage of 5V volts.A component pin count of 16 is found on this turn signal switch.A conductor terminates at GULL WING.As a type of supply, Single is employed.There are 16 pins on it.It is mounted in the way of Surface Mount.I would like to refer to the logic switch as a member of the LS family.In this signal multiplexer, there are 10 bits that are provided.During mux switch's normal operation, 5V is provided with a power supply.For the turn signal switch's operation, there are 10 outputs.No external influence consumes 7mA current of multiplexer ic.The performance of the multiplexers of a system can be reliably achieved with a supply voltage of 5V.It has 4 inputs.In accordance with TR, switches can be packaged.Additionally, it improves the characteristics of ION MAX=80MA @ VOL MAX=3V.This mux switch configuration has 1 elements.
