1 Wire one half the 1 side of the 74LS74 Dual PositiveEdgeTr

1. Wire one half (the 1 side) of the 74LS74 Dual Positive-Edge-Triggered D Flip-Flop according to the following, (Again, see the Multisim component.) As before, use interactive constants and digital probes in place of switches and LEDs. Vcc 74L S74 LED2 Figure 6-74LS74 Wiring Diagram Verify the operator of the 74LS74 as follows. It may be helpful to note your observations. a. Set to LOW the CLR and SET inputs one at a time while monitoring the effect on 2. the Q outputs for various combinations of the D and CK (CLOCK) inputs. b. Set CLR and SET high for the remainder of this procedure. c. With CK set high, change the D input between logic 0 and 1, noting the effect on d. With CK set low, change the D input between 0 and 1 noting the effect on the e. Set D to the opposite state of Q (CK is still low), then switch CK low to high f. Without changing D, toggle the CK input between high and low several times g. Again, set D to the opposite of Q, then switch CK from 0 to 1 to 0, noting the the outputs. outputs noting the effect on the outputs. noting the effect on the output. effect.
