74AC139PC 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.Tube represents its packaging.Digital switch ic uses a Through Hole mounting method.As the analog part, the circuit uses an analog IC Decoder/Demultiplexer.By keeping the operating temperature at -40°C~85°C, turn signal switch will not be affected by external factors.With a supply voltage of 2V~6V, designers have greater flexibility of digital controlled switch.Multiplexers of the 74AC series can be used in a wide range of applications.Its basic configuration includes terminations in the 16 range.In this case, 3.3V is the voltage supplied to the multiplexer's system.A component pin count of 16 is found on this turn signal switch.In the AC family, the logic switch is included.In order to prevent unnecessary failures, it is recommended that the minimal supply voltage (Vsup) be kept at 2V.Vsup (maximum supply voltage) should be kept as 6V to prevent unnecessary failures.
