MC74AC139DR2 Overview
It is included in the 16-SOIC (0.154, 3.90mm Width) in order to save board space.The package is in the form of Tape & Reel (TR).Surface Mount is the mounting method digital switch ic uses.Decoder/Demultiplexer is the analog IC that the multiplexers uses.When the operating temperature is kept at -40°C~85°C, turn signal switch will not be susceptible to external factors.When operated with a 2V~6V supply voltage, digital controlled switch provides digital controlled switch's superior flexibility for designers.Multiplexers in the 74AC series are suitable for a wide range of applications.It is designed with 16 terminations as part of its basic configuration.In multiplexer's system, 5V is the voltage supplied.In this turn signal switch, there are 16 component pins.At the end of a conductor, it uses GULL WING as the point where the conductor ends.I would like to refer to the logic switch as a member of the AC family.It is recommended that the minimum supply voltage (Vsup) be kept at 2V to avoid some unnecessary failures.The maximal supply voltage (Vsup) should be kept at 6V to avoid some unnecessary failures.
