Its selection lines is therefore made of a single bit. The simplest multiplexer is the 2: From there the sum of minterms and the logic function for a 2: Multiplexers generally only come in a few common sizes.

Multiplexer (MUX) – WikiChip

A multiplexer with 2 N input lines requires N select lines. A common multiplexer is the 8: MUXes are core components in most digital systems as they can be used to pass the correct signal based on some conditional logic.

A 7415 mux or a data selector or input selector is a combinational circuit device that selects one of N inputs and provides it on its output. This section requires expansion; you can help adding the missing info. While smaller 74115, this multiplexer is also nonrestoring. Consider a register file with 32 registers where we only want to select a single register at any given time.


A single inverter is used to invert the selection line value to one of the gates so that only one of them e. Multiplexers are useful in any application uc which data must be chosen from multiple sources to a single destination.

Additionally multiplexers have also found their way to various other circuits such as adders.

Typically larger multiplxers over 8 or 16 inputs are built using smaller multiplxers using a multiplexer tree. Vcc is on pin 16 and GND is on pin 8. For example, consider a data bus that is connected to multiple memory storage units. Retrieved from ” https: It does mean that icc multiplexers with odd number of inputs, some selection line combinations are not allowed e.


Many different variations of multiplexers exist. An enable input makes the multiplexer operate. Even in ASIC design, arbitrary sized multiplexers are not always offered.

It’s often desirable to add an enable or strobe input EN to a multiplexer. This section is empty; you can help add the missing info by editing this page.


A set of select lines are then used to choose which of kc inputs gets produced as output. Where Equation m Subscript k is the kth minterm of the variable. uc

A set of inputs called select lines determine which input should be passed to the output. Such multiplexer can be design from four 8: Multiplexer Typical Symbol 2: A multiplxer is a device that receives multiple inputs from usually different sources.

The K-Map for that truth table is provided on the left. One can use a multiplexer to select which of those lines should be going to the shared data bus.

Those types of multiplexers can be hooked up directly to a shared bus ensuring that only one signal is being generated on the bus at any given time. There are many way to construct a 4: The top transmission gate controls if the input from A should pass to the output while the bottom transmission gate does the same for the B input. For a multiplexer with Equation upper N inputs, you also need Equation left ceiling log Subscript 2 Baseline left-parenthesis upper N right-parenthesis right ceiling selection lines.
