74AC139 Overview
As a means of saving space, digital switch is provided in the Die.The package is packaged in accordance with Tray.The mounting method digital switch ic uses is Surface Mount.The analog IC in the multiplexers is identified as Decoder/Demultiplexer.The operating temperature will not be affected by external factors when turn signal switch is set to -40°C~85°C.Designers have greater flexibility when digital controlled switch operates at a 2V~6V supply voltage.The multiplexers from 74AC series can be used for a wide range of applications.As parts of its basic configuration, 16 terminations are desgined.The multiplexer's system is powered by 3.3V voltage.GULL WING is used as the point at which the conductors come to an end as part of this formula.The logic switch is included into the family of AC.To prevent unnecessary failures, it is recommended that the minimum supply voltage (Vsup) remain at 2V.The maximal supply voltage (Vsup) should be kept at 6V to avoid some unnecessary failures.In order to maintain mux switch's normal operation, power is provided to 3.3/5V.In electronic terms, the digital switch ic is classified as Decoder/Drivers.
