18 Laboratory Five Latches and Flip-flops Objectives The main objective of this laboratory is to explore the properties of latches and flips-flops. To do this you will construct several circuits, apply different signals to them and observe the results. Activities Part 1: Latch The first activity is to construct the latch circuit shown on page 159 of the textbook. Here it is:
19 After you have constructed the latch attach an LED and resistor to each of its outputs and observe the behavior of the latch as +5 and ground are applied to its inputs. Based on the description of the latch in the textbook we expect the latch to behave in a predictable way as long as only one of its inputs is a 1. Is this the behavior that you observe? Now we will examine what happens when both of the inputs are set to 1 at the same time. Connect the clock circuit from laboratory three to both of the inputs to the latch. Op-amp LM 358chip
