SN74AS138N 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.As a result, it is packaged in the way of Tube.digital switch ic uses the method of Through Hole for mounting.The analog IC used in the multiplexers can be referred to as Decoder/Demultiplexer.In the case of 0°C~70°C, turn signal switch will not be affected by external factors.When digital controlled switch operates at 4.5V~5.5V, designers have superior flexibility.Multiplexers from the 74AS series can be used in a wide range of applications.The part number for 74AS138 can be used to find its logic switch related parts as well.In this case, Single is employed as the supply type.This multiplexer ic has 16 pins configured.As you can see, it is mounted in the direction of Through Hole.There are 8 bits signal multiplexer provides.This turn signal switch has 8 outputs designed for its operation.The performance of the multiplexers can be reliably maintained at a voltage of 5V.A multiplexer such as this has 3 inputs available.As a voltage level input, the multiplexers have 3 lines.There are 8 output lines designed to serve as the source of the signal.A total of 1 transmission channels are available in the turn signal switch's circuit.The maximum operating temperature of 70°C is acceptable for this signal switch.In order to maintain a minimal operating temperature, the temperature of the multiplexer should be set to 0°C.Device specifications specify 5.5V as the maximum supply voltage for the signal switches.In compliance with the applicable device specification, the digital swith operates at a minimum supply voltage of 4.5V.In the mux switch configuration, there are 1 elements.During normal operation, the digitalswitch consists of 1 circuits.
