Logic-signal switches, multiplexers, decoders are widely used in electronics circuits, elevators, display systems and many other fields such as automobiles and telephone systems due to their lightning-fast speed and precise timing in signal handling. A 74HC154N 652 is a high speed CMOS integrated circuit which has four digital inputs and two outputs. It is usually used to decode and demultiplex binary coded decimal (BCD) inputs and provides two logic-level outputs at the same time which come from two; two-input multiplexers.

The 74HC154N is capable of demultiplexing digital signals of 4 bits and converting them into two 8-channel 8-bit output logic signals. Its main application is to receive digital signals from buses and convert them into logic levels. The various logic families where the 74HC154N is used include Non-volatile RAM, Clock & Timer, Component Counters, Pattern Generator and Memory. The 74HC154N is also found in applications such as industry controllers, process control systems, industrial automation and communications.

The working principle of the 74HC154N is simple. First, a binary coded decimal input code is received by the multiplexer. This code is then decoded and the outputs are provided in the form of two separate logic signals which could be either low or high. The logic signals ported out of the multiplexer are used to perform a variety of operations. In essence, it works as a demultiplexer. Furthermore, its small size, low power consumption and fast switching speeds make this chip highly desirable for low power digital systems.

The 74HC154N can be used in a number of different circuits. It can be used as a digital multiplexer to select the appropriate digital inputs. A circuit with two 74HC154N can be used to take the inputs from the 4-to-16 decoder and output 4 logic signals simultaneously. Additionally, the 74HC154N is often used to build binary-to-BCD converters that accept 4-bit binary inputs and generate BCD outputs.

The 74HC154N is a versatile chip that can be used for a number of purposes. It is well suited for applications where a low-cost solution is required and can be used to increase the speed and accuracy of digital systems. Its small size and low power consumption make it an ideal choice for many applications.
