These two conditions must be met to reliably clock data from D to Q of the Flip-Flop. Sorry, realize c4d031 is a long time later, but I just found this thread when doing a search for my own schem. Since our example shift register uses positive edge sensitive storage elements, the output Q follows the D input when the clock transitions from low to high as shown by the up arrows on the diagram above.

The D register does not see a one until time t 2at which time Q goes high. Q B goes high at t 3 due to a 1 from the previous stage. Whatever is driving the clock must have a minimum source and sink current of 1 milliampere to drive this capacitance.

Its hard to find the MC here. Ahh it’s driving me insane.

Feb 02, Posts: Would it be possible to have a LED output on the stages? For recirculation, the REC IN terminal can be connected to pin 6 of this register or any cascaded register. The falling edge can be ignored.

At dtasheet 1 Q goes to a zero if it is not already zero.

The datashdet pairs of arrows show that a three-stage shift register temporarily stores 3-bits of data and delays it by three clock periods from input to output. Dedicated to experimental electro-acoustic and electronic music. To get a full bit shift register the output of one shift register must be cascaded to the input of another and so on until all stages create a single darasheet register as shown below.

There is no doubt what logic level is present at clock time because the data is stable well before and after the clock edge. Manufacturers of digital logic make available information about their parts in dztasheet sheets, formerly only available in a collection called a data book. May 25, Posts: For some general information about shift registers: Apr 15, Posts: WE Athe write enable for section A, is grounded. Wed Oct 12, 5: A major feature is a data selector which is at the data input to the shift register.


If you click through and buy from our affiliate partnerswe earn a small commission. In 64 successive clock pulses, entered data will appear as an output on pin 6 and as its complement on pin 7.

I found this schematic http: Pin 6 and pin 7 can each drive one TTL load. Mon Oct cc4031, 5: Data enters the register on the ground-to- positive transition positive edge of the clock. Tue Oct 15, 9: See the full datasheet for details.

It is very easy to see Q follow D at clock time above. There was a very lengthy discussion about these on the sound of logic forums. This is seldom the case in multi-stage shift registers. The short oversimplified answer is that it sees the data that was present at D prior to the clock.

Oct 16, Posts: Tue Sep 11, 8: A CDb dual bit shift register is shown above. Three type D Flip-Flops are cascaded Q to D and the clocks paralleled to form a three-stage shift vatasheet above.

Crystal oscillator or silicon oscillator? The clock for section A is CL A. Too weird to live, and too rare to die.
