DM74ALS138N Overview
Due to the fact that it is provided in the 16-DIP (0.300, 7.62mm), digital switch allows the board to be compacted.It is packaged in the way of Tube.For mounting, digital switch ic uses the method Through Hole.As the analog part, the circuit uses an analog IC Decoder/Demultiplexer.By keeping the operating temperature at 0°C~70°C, turn signal switch will not be affected by external factors.With a supply voltage of 4.5V~5.5V, designers have greater flexibility of digital controlled switch.These multiplexers are members of the 74ALS series, which provide extensive application potential.In addition, it also has a base part number of 74ALS138, which can be used to find related parts.In this case, the supply type is Single.A configuration of 16 pins is used.The multiplexer ic is mounted in the direction of Through Hole.For the turn signal switch's operation, there are 8 outputs.Providing a supply voltage of 5V can provide reliable performance of the multiplexers.The multiplexer provides 3 inputs.In order to accept voltage levels, the multiplexers have input lines 3 on the board.In this case, the signal source has a total of 8 output lines.The maximum temperature for this signal switch is 70°C.The minimal operating temperature of the multiplexer should be maintained at 0°C.Based on the device specifications, the signal switches is designed to operate at 5.5V maximum supply voltage.Typical device specifications specify a voltage supply of 4.5V for the digital swith.Configuration elements for the mux switch consist of 1.To operate the digitalswitch normally, 1 circuits are formed.
