1) D Flip-Flop: • Plug in the 74LS74 D-type flip-flop and connect ground to pin 7 and 5V to pin 14 as usual. This is a two-circuit DIP. Referring to the 74LS74 pin-out diagram, choose one of the two D FFs on the chip and connect the input switches to the D and Preset inputs. Since the preset is negative-true logic input, make sure the switch is set to 1. Connect the pulse switches (the negative-true outputs) to the Clock and Clear inputs. The Q and Q' outputs should be connected to LED inputs. For this online version: • Go to the Memory folder to drop a D Flip-Flop onto the workspace. • Go to Wiring (or the shortcut menu) and drop two source pins (Square) onto the breadboard, one for the D input and the other for the Preset. Be sure to add labels. • Logisim is NOT negative true input. Adjust your circuit accordingly. • Go to the Input/Output folder and drop two "Buttons" (Square) onto the breadboard, one for the Clock (triangle on Flip Flip) and one for the clear. Be sure to add labels. • Go to the Input/Output folder, and drop two LED onto the workspace. Connect on to the Q output and one to the Q' output.
