How do you implement latch with mux?

How do you implement latch with mux?

This means we can easily make a latch using 2:1 MUX like following. When CLK is high it passes through D to O and when CLK is off, O is fed back to D0 input of mux, hence O appears back at the output, in other words, we retain the value of O when CLK is off. This is what exactly latch does.

How do you make an AND gate using a mux?

All we need to do is zero out the second product term. We can achieve this by making B as ‘0’. We can tie B input of MUX to zero. Thus we can get an AND gate by tying B input of MUX to zero, resulting circuit is AND gate which ANDs input A and mux select S.

What is latch What is the difference between latch and flip flop?

The major difference between flip-flop and latch is that the flip-flop is an edge-triggered type of memory circuit while the latch is a level-triggered type. It means that the output of a latch changes whenever the input changes.

Why D latch has less output?

Since the R input of the S-R circuitry has been done away with, this latch has no “invalid” or “illegal” state. When the enable input is made low (0), the latch ignores the status of the D input and merrily holds the stored bit value, outputting at the stored value at Q, and its inverse on output not-Q.

Could you wire up a 2 1 mux to implement an AND gate?

2-input AND gate implementation using 2:1 mux: Figure 1 below shows the truth table of a 2-input AND gate. If we observe carefully, OUT equals ‘0’ when A is ‘0’. And OUT follows B when A is ‘1’. So, if we connect A to the select pin of a 2:1 mux, AND gate will be implemented if we connect D0 to ‘0’ and D1 to ‘B’.

How would you implement NOT gate using mux?

The only inverting path in a multiplexer is from select to output. To implement NOT gate with the help of a mux, we just need to enable this inverting path. This will happen if we connect D0 to ‘1’ and D1 to ‘0’.

What is the difference between D latch and D flip-flop?

The D-type Flip Flop Summary The difference between a D-type latch and a D-type flip-flop is that a latch does not have a clock signal to change state whereas a flip-flop always does. The D flip-flop is an edge triggered device which transfers input data to Q on clock rising or falling edge.

Which consumes more power latch or flip-flop?

More power is consumed by the Flip-Flop. The latch is sensitive to the input and as long as it is ‘On’, we can transmit the data. Flip-Flop is sensitive to the clock signals and until there is a change in the input clock signal, it never changes the output.
