SN74F138NS Overview
The reason it is provided is that the board space can be saved by placing digital switch in the 16-SOIC (0.209, 5.30mm Width).It is packaged according to the Tube method.As far as mounting is concerned, digital switch ic uses Surface Mount.As the analog part, the circuit uses an analog IC Decoder/Demultiplexer.When the operating temperature is kept at 0°C~70°C TA, the machine will not be sensturn signal switchive to external influences.Designers have greater flexibility when digital controlled switch operates at a 4.5V~5.5V supply voltage.These multiplexers are members of the 74F series, which provide extensive application potential.The basic configuration of this system includes 16 terminations.There is a base part number of 74F138 which can also be used in order to locate the logic switch that are related to this item.For multiplexer's system, a voltage of 5V is supplied.This turn signal switch has 16 component pins.At the end of a conductor, it uses GULL WING as the point where the conductor ends.A configuration of 16 pins is used.The logic switch is a member of the F/FAST family.The multiplexer ic provides 8 bits.To avoid unnecessary failures, keep the supply voltage at 4.5V (Vsup).It is advisable to keep the maximum supply voltage (Vsup) at 5.5V in order to prevent some unnecessary failures.The power supply of 5V is provided for mux switch's normal operation.This is a signal switch that is categorized as Decoder/Drivers.TR is used to package the switches.
