MC74HC139AN Overview
This is a relatively small item of digital switch that is included in the 16-DIP (0.300, 7.62mm) in order to save space on the board.In this case, it is packaged as Tube.Through Hole is the mounting method digital switch ic uses.As the analog part, the circuit uses an analog IC Decoder/Demultiplexer.If the operating temperature is maintained at -55°C~125°C, turn signal switch will not be susceptible to external factors.With a supply voltage of 2V~6V, designers have greater flexibility of digital controlled switch.The multiplexers from 74HC series can be used for a wide range of applications.Its basic configuration includes terminations in the 16 range.The multiplexer's system works with 4.5V voltage.This turn signal switch has 16 component pins.The logic switch belongs to the family of HC/UH.It is recommended that the minimum supply voltage (Vsup) be kept at 2V to avoid some unnecessary failures.To avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 6V.
