Q B goes high at t 3 due to a 1 from the previous stage.

Thank you so much. It’s on the Blog of ConcreteDog: Hold time is met as long as the propagation delay of the previous D FF is greater than the hold time.

Note the taps at the 16th, 32nd, and 48th stages. Hey, I was wondering how to build one of these fancy tap loopers. Datashfet short oversimplified answer is that it sees the data that was present at D prior to the clock.

They will store a bit of data for each register. WE Bthe write enable, is grounded. Thus, the 5-bit stages could be used as 4-bit shift registers.

Refer to the figure below. The following data was extracted from the CDb data sheet for operation at 5V DCwhich serves as an example to illustrate timing. Mon Oct 14, 6: There are also the 1 to 64 bit variable length and bit. In particular, D of stage A sees a logic 0which is clocked to Q A where it remains until time t 2. Wed Oct cx4031, 5: Sorry, realize it is a long time datashest, but I just found this thread when doing a search for my own schem. A major feature is a data selector which is at the data input to the shift register.

For anyone who looks up this design, or is otherwise interested, I finally put up a post on my blog about this design: Too weird to live, and too rare to die.

The question that arises is how did this data pattern get into the shift register in the first place? Its hard to find the MC here. There is no problem meeting the setup time of 60ns as the data at D has been there for the whole previous clock period if it comes from another shift register stage.

Since our example shift register uses positive edge sensitive storage elements, the output Q follows the D input when the clock transitions from dattasheet to high as shown by the up arrows on the diagram datqsheet. Alternately, the Mode control can be used to select the data stream on pin 1 Mode positive or on pin 15 Mode grounded. Thanks for sharring the link to the other forum, but i would need some schematics, datasheeh don’t really see how to wire this kind of ic to other lunetta’s stuff!


WE Athe write enable for section A, is grounded. Serial-in, Serial-out Chapter 12 – Shift Registers. Pin 6 and pin 7 can each drive one TTL load. The correct waveform is Q C. Find out with this project.

This is a fully static shift register with the ability to recirculate data.


Data at D driven by another stage Q will not change any faster than ns for the CDb. Both are hard datassheet find but should add even more variety to this awesome design. Nov 02, Posts: Whatever is driving the clock must have a minimum source and sink current of 1 milliampere to drive this capacitance.
