IC 74151 PDF

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.

Output same as input, High-Z 7151. Such multiplexer can be design from four 8: MUXes are core components in most digital systems as they can be used to pass the correct signal based on some conditional logic.

One can use a multiplexer to select which of those lines should be going to the shared data bus. Same day dispatch for Most orders if payment done before 4 pm. A truth table is provided on the right.

74151 Data Selectors/Multiplexers

Its selection lines is therefore made of a single bit. Note that the implementation below is an active-low. A multiplxer is a device that receives multiple inputs from usually different sources.

Multiplexer | Electronics Tutorial

A multiplexer with 2 N input lines requires N select lines. Have You Seen Product Page: Various multiplexers are available in discrete chips as well for both series and series. The A have a strobe input which must be at a low logic level to enable these devices. Even in ASIC design, kc sized multiplexers are not always offered.


A high level at the strobe forces 7411 W output high and the Y output as applicable low. This page was last modified on 18 Novemberat It’s often 7415 to add an enable or strobe 7415 EN to a multiplexer. 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. Typically larger multiplxers over 8 or 16 inputs are built using smaller multiplxers using a multiplexer tree. Consider a register file with 32 registers where we only want to select a single register at any given time.

While smaller overall, this multiplexer is also nonrestoring. Additionally multiplexers have also found their way to various other circuits such as adders. Multiplexer Typical Symbol 2: A common multiplexer is the 8: Delivery Normally takes 2 to 7 working days depending upon your location.

An enable input makes the multiplexer operate. Multiplexers are useful in any application iv which data must be chosen from multiple sources to a single destination. A single inverter is used to invert the selection line value to one of the gates so that only one of them e. Id K-Map for that truth table is provided on the left. Large multiplexers can always be built from a collection of smaller ones.

Complementary outputs, High-Z Enable.

Multiplexers generally only come in a few common sizes. Pins 5 iv 6 are the outputs, the output on pin 6 is the inverted version of the output on pin 5.


From there the sum of minterms and the logic function for a 2: GST Invoice on all Purchase. 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. For a multiplexer with Equation upper N inputs, you also need Equation left ceiling log Subscript 2 Baseline left-parenthesis upper N right-parenthesis 7415 ceiling selection lines. This section is empty; you can help add the missing info by editing this page.

For example, consider a data bus that is connected to multiple memory storage units. A set of select lines are then used to choose which of those inputs gets produced as output. Many different variations of multiplexers exist. The enable is on pin 7.

Multiplexer (MUX) – WikiChip

The simplest multiplexer is the 2: Features of selects one-of-eight data lines Performs parallel-to-serial conversion Permits multiplexing from N lines to one line Also for use as Boolean function generator Typical average propagation delay time, data input to W output: Write a review 0 reviews. The A incorporates address buffers which have symmetrical propagation delay times through ix complementary paths.

Vcc is on pin 16 and GND is on pin 8.
