                                                MC74ACT139D Overview
Due to the fact that it is provided in the 16-SOIC (0.154, 3.90mm Width), digital switch allows the board to be compacted.As a result, it is packaged in the way of Tube.In terms of mounting, digital switch ic uses the method of Surface Mount.the multiplexers uses IC Decoder/Demultiplexer as the analog IC.The operating temperature of -40°C~85°C will not be susceptible to external factors.When digital controlled switch operates at 4.5V~5.5V, designers are provided with a greater degree of flexibility.Several applications are possible for 74ACT series multiplexers.Among its basic features are 16 terminations.To find signal switch's related components, a base part number of 74ACT139 may also be used.For multiplexer's system, 5V voltage is supplied.Currently, this turn signal switch has a total of 16 component pins.It is the end of conductors that is represented by GULL WING.There is a supply type of Single employed as part of this supply.With 16 pins, it is configured.The multiplexer ic is mounted in the direction of Surface Mount.The logic switch is a member of the family of ACT.Normally, 5V is powered by a battery.The digital switch ic is a part of an electronic system classified as Decoder/Drivers.If the supply voltage is set to 5V, reliable performance of the multiplexers can be achieved.In order to accept voltage levels, the multiplexers have input lines 1 on the board.A signal source has 4 output lines.
