Logic - Signal Switches, Multiplexers, DecodersThe 74LV138BQ,115 is a high performance 3-to-8 line decoder/demultiplexer designed to have very low power dissipation and very high noise immunity. It boasts a power supply voltage versus dissipation of 3.3V to 8V. This makes this device perfect to use in applications with low power and noise immunity requirements.The functionality of the 74LV138BQ,115 is based on the basic principles of logic and signal switches and multiplexers. The chip acts as a decoder, which takes inputs from two signals and sends the output to an 8 line multiplexer. The 8 lines are connected to 8 individual gates. The two inputs can be either an active HI or active LOW signal. When an input is received, the corresponding gate is activated and the resulting signal is sent out to the multiplexer.Once the signal is sent out to the multiplexer, it is then converted, depending on the logic state of the individual line, into one of the 8 possible outputs. This output can then be used to drive a high power load. The 74LV138BQ,115 enables 8 different combinations of output signals by routing them to their respective places.An important feature of the 74LV138BQ,115 is the ability to have level shifting between 3.3V and 8V. This means that the logic level of the signal switches and multiplexer can be adjusted to match the power level of the circuit. This helps to reduce power losses and also prevent switching noise.The 74LV138BQ,115 can be used in a wide range of applications. These include motor control, signal routing, bus arbitration and switching, and memory access. Additionally, it can be used for the creation of logic gates and signal processing.In terms of power consumption, the 74LV138BQ,115 requires only 14mA at 8V, which is much lower than most decoders and multiplexers. This makes it very efficient for low power applications. Additionally, it features a temperature range from -40°C to +85°C and has a self-protection circuit against reverse supply connection.Overall, the 74LV138BQ,115 is a state-of-the-art decoder/demultiplexer that should come in handy for any application that requires low power levels and has noise immunity requirements. Its level shifting feature helps the device to remain compatible with the logic levels of the circuit. With its efficiency and dependability, the 74LV138BQ,115 is a valuable addition to any logic and signal switch and multiplexer application.
