CD74AC139E Overview
The reason it is provided is that the board space can be saved by placing digital switch in the 16-DIP (0.300, 7.62mm).It is packaged in the way of Tube.digital switch ic uses the method of Through Hole for mounting.the multiplexers uses an analog IC Decoder/Demultiplexer.By keeping the operating temperature at -55°C~125°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 1.5V~5.5V, designers are provided with a greater degree of flexibility.As a member of 74AC series, the multiplexers can be used for a wide range of applications.As parts of its basic configuration, 16 terminations are desgined.The turn signal switch is supplied with a voltage of 5V volts.The logic switch is included into the family of AC.Vsup should be kept at 1.5V to prevent some unnecessary failures.The maximal supply voltage (Vsup) should be kept at 5.5V to avoid some unnecessary failures.
