In LogicWorks, build this design using the chip schematics.ĭefine the term “flip-flop.” What are the different types of flip-flops? What is the difference between a flip-flop and a latch?Ĭharacteristic table of this D Flip-Flop (is yours positive- or negative-edge triggered?)Ĭhip schematic circuit for master-slave D Flip-FlopĮxplain how the master-slave scheme works to ensure changes only occur on a clock edgeĬomplete a lab report that contains the following sections. This can be built with just two Nand chips and one Not chip. The design for a master-slave D flip-flop is provided for you in the slides. Identify the special feature of the logic circuit that makes these sequential circuits. D latchesĭiscuss why these are sequential circuits. Side-by-side comparison of the chip schematic circuitsĭiscuss the advantages/disadvantages of S-R vs. Use characteristic tables to outline the differences between S-R and D gated latches What is the advantage of having an Enable switch? Now convert this circuit into a gated D latch (hint: all the NAND gates remain in place and you need to add just one Not gate).ĭefine the terms “latch” and “gated latch” and explain how these can act as memory. What happens when EN=0? What happens when EN=1? What do S and R accomplish? What happens when both S and R are High? In LogicWorks, build this design using the chip schematics. The design for a gated S-R latch made entirely from NAND gates is provided for you in the slides. Topics: Latches and flip-flops built from gates
