Complete circuits for Multiplexer and De-multiplexer circuits using TTL IC and This Data Selector Multiplexer contains full on-chip decod- ing to select one-of- eight data sources as a result of a unique three-bit binary code at the Select. A typical IC is an 8-to-1 multiplexer with eight inputs and two outputs. The two outputs are active low and active high outputs. It has three.

The A incorporates address buffers which have symmetrical propagation delay times through the complementary paths. HTML is not translated! The enable is on pin 7. Such multiplexer can be design from four 8: While smaller overall, this multiplexer is also nonrestoring.

Have You Seen Product Page: A set of inputs called select lines determine which input should be passed to the output. One can use a multiplexer to select which of those lines should be going to the shared data bus. The K-Map for that truth table is provided on the left. MUXes are core components in most digital systems as they can be used to pass the correct signal based on some conditional logic.


A multiplexer iv 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. Various multiplexers are available in discrete chips as well for both series and series. Note that the implementation below is an active-low. Privacy policy About WikiChip Disclaimers.

For example, consider a data bus that is connected to multiple memory storage units. A multiplexer with 2 N input lines requires N select lines.


Output same as input, High-Z Enable. This section is empty; you can help add the missing info by editing this page.

Additionally multiplexers have also found their way to various other circuits such as adders. Pins 5 and 6 are the outputs, the output on pin 6 is the inverted version of the output on pin 5.

Delivery Normally takes 2 to 7 working days depending upon your location.

GST Invoice on all Purchase. The top transmission gate controls if the input from A should pass to the output while the bottom i gate does the same for the B input.


MUX with an SR latch. Kc from ” https: A high level at the strobe forces the W output high and the Y output as applicable low. Multiplexer Typical Symbol 2: There are many way to construct a 4: It also has complementary W and Y outputs, whereas the has an inverted W output only.

74HC151 IC – 8 – Input Multiplexer IC (74151 IC)

So you will be eligible to take input tax credit. Write a review 0 reviews.

Even in ASIC design, arbitrary sized multiplexers are not always offered. Signals to the select lines usually come from a control unit that determines which, if any, of the signals should be routed to some destination.

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.
