1. A 0.01-F capacitor is recommended by TTL manufacturers for ________ the power supply.
2. Why does the data sheet for the 7476 only give a minimum value for the clock pulse width (both HIGH and LOW)?
3. Why is the Schmitt trigger needed in the 60-Hz TTL-level clock pulse generator?
4. The main concern when using a pull-down resistor is:
5. Look up the propagation delay from the clock to the output for the 7476. Are the HIGH-to-LOW and LOW-to-HIGH propagation delays the same?
6. What would be the output voltage of a 7814 voltage regulator?
7. The purpose of a pull-up resistor is to keep a terminal at a ________ level when it would normally be at a ________ level.
8. Setup time specifies:
9. Can the automatic RC circuit be used to set a flip-flop rather than reset the flip-flop?
10. A Schmitt trigger:
11. A settable flip-flop's normal starting state when power is first applied to a circuit is always the ________ state.
12. In the automatic reset circuit for a flip-flop, how long does it take the capacitor to completely charge?
13. The output of a standard TTL NAND gate is used to pull an LED indicator LOW. The LED is in series with a 470- resistor. What is the current in the circuit when the LED is on?
14. When the inputs to a flip-flop are changing at the same time that the active trigger edge of the input clock is making its transition, this condition is called:
15. Is the propagation delay from the clock to the output for the 7476 the same as the delay from the set or reset to the output?
16. What is the difference between setup time and hold time?
17. Define a race condition for a flip-flop.
18. Which of the following flip-flop timing parameters indicates the time it takes a Q output to respond to a Cp input?
19. How much setup time (ts) is required for the 74LS76?
20. Why should a LED be pulled LOW from a logic gate rather than pulled HIGH?
21. What is the major advantage of the J-K flip-flop over the S-R flip-flop?
22. Decoupling capacitors should be tied from VCC on one device to ground on a different device.
23. One example for the use of a Schmitt trigger is as a(n):
24. TTL requires a constant supply voltage of 8.0 V.
25. A transfer function graph illustrates the most important specifications for the Schmitt trigger devices.
