MC74AC139D Overview
For the purpose of saving board space, digital switch is included in the 16-SOIC (0.154, 3.90mm Width).The package is in the form of Tube.Mounting is performed using Surface Mount.Decoder/Demultiplexer is the analog IC that the multiplexers uses.By maintaining the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.Designers have greater flexibility when digital controlled switch operates at a 2V~6V supply voltage.Multiplexers of the 74AC series can be used in a wide range of applications.Among its basic features are 16 terminations.As its base part number is 74AC139, logic switch can also be used to find its related parts.The multiplexer's system is powered by 5V voltage.Signal switch has 16 component pins.A conductor terminates at GULL WING.In this case, Single is employed as the supply type.This multiplexer ic is configured with 16 pins.This unit is mounted in the way of Surface Mount.The logic switch belongs to the family of AC.To avoid unnecessary failures, keep the supply voltage at 2V (Vsup).It is advisable to keep the maximum supply voltage (Vsup) at 6V in order to prevent some unnecessary failures.A power supply is provided for mux switch's normal operation of 3.3/5V.I would classify the digital switch ic as an electronic part belonging to the Decoder/Drivers category.RAIL is used to package the switches.A voltage level can be inserted into the 1 input lines of multiplexers.As the signal source, there are 4 output lines.
