CD4053BCMX (also known as CD4053) is a monolithic CMOS integrated circuit that is designed to be used as an analog multiplexer/demultiplexer (MUX/DEMUX), or switch. It has the ability to rout signals from one input to one of eight outputs, or from one of eight inputs to one output. The device contains a pair of 3:8 logic-level translating multiplexers, three logic-level transmitting D-type latches, and three logic-level translating outputs. Its operating temperature range is -55℃ to +125℃, its power supply voltage is 3.0V to 18V, and its package is SOIC-14.

The main application field of CD4053BCMX is to switch multiple signal paths between a signal source, such as a microprocessor, and multiple signal sinks, such as a motor control circuit, to control the selection of electrical signals from one source to one of eight output sources at a time. It can be used to control the selection of switching logic states when there are more than two competing logic states in multiple circuits, for example, to route a data bit stream from one digital source to one of 8 path outputs. Furthermore, the CD4053BCMX can be used to implement various combinations of logic gates using logical operations, such as AND, OR, XOR, and NOT gates.

The working principle of CD4053BCMX is relatively simple. It uses two 3:8 multiplexers to switch a single input to one of eight output lines. The two multiplexers are controlled by three digital logic inputs A,B,C. Each logic input is used to select one of the 8 output lines. With inputs A,B,C tied to LOW (0), the three output lines will be tied to LOW (0), effectively routing the input signal to the selected output line. With other combinations of the three logic inputs, other output lines can be individually selected to have the input signal routed to it.

The CD4053BCMX also contains three D-type latches and three logic-level transmitting outputs for logic signals control. The three latches are used to store the three logic signals from the A,B,C inputs to keep them from changing until a new selection command is issued. The three logic-level transmitting outputs can further be used to explicitly control the output lines selected by the multiplexer.

In summary, CD4053BCMX is a versatile and efficient analog multiplexer/demultiplexer that can be used to switch multiple signal paths between a signal source and multiple signal sinks. It can also be used to control the selection of logic states when there are more than two competing logic states in multiple circuits. Its operating temperature range is -55℃ to +125℃, its power supply voltage is 3.0V to 18V, and its package is SOIC-14.
