Logic devices have a wide range of applications in electronics and computing. The SN74LS348NSR is a logic device known for its wide range of applications in different fields and its versatile working principle.

It serves as an 8 to 3 bit decoder with active Low output. Either of the eight inputs can be selected, giving one of the three outputs.

The SN74LS348NSR is a remarkable tool of data handling, being useful in applications like multiplexers and output decoding.

This device is used in automotive industry and in industries associated with avionics. It is also found in applications related to communication technologies and in different telecom applications like time division multiplexing.

Due to its versatility and wide range of application field, it is known to be a costly device.

Working principle

The SN74LS348NSR is a logic device that works based on the principle of Boolean logic. The input signals are first converted into a specific logic pattern and this logic pattern is then converted into a certain output as assigned.

This device has a number of components including logic gates and transistors. In its simplest form, it consists of two parts: a logic circuit and a decoder.

The logic circuit consists of two components: the multiplexer and the decoder. The multiplexer receives eight inputs of varying logic level and produces a single output based on this input.

The decoder takes this single output from the multiplexer and converts it into three logical outputs. These three outputs are then used for the intended purpose, such as driving a mechanical movie display or controlling a digital device.

Multiplexer

The multiplexer accepts logic inputs of varying logic level and produces a single output. Depending on the logic level of the inputs, the multiplexer will create different combinations of logic levels at the output.

For instance, if the inputs were 1, 0, and 1, then the multiplexer would create a logical OR of these three inputs and create a logical 1 output. This same process is repeated for all eight inputs, thus producing a single output.

Decoder

The decoder then takes the single output from the multiplexer and converts it into three outputs. The first output will represent a specific logic level, while the other two will represent the two logic levels that the first output does not represent.

For instance, if the first output is a 0, then the decoder will produce two 1s at the other outputs. Similarly, if the first output is a 1, then the decoder will produce two 0s at the other outputs.
