Exam 8: Integrated-Circuit Logic Families

Examination of the input and output signals of an IC inverter reveals a delay from the time the input goes LOW until the output goes HIGH. The delay between these two signals should be measured at the amplitude points and be labeled .

As a general rule, the lower the value of the speed- power product, the better the device because of its:

The inherent signal delays produced by a logic device are identified as:

The chief disadvantage of MOS technology is:

An identification number of 74HCT would identify the series as a:

Power supply decoupling consists of radio- frequency capacitors connected from V_cc to ground to "short" high- frequency voltage spikes to ground.

A quantitative measure of noise immunity is called noise______.

-Refer to Table 8- 1. Which series is capable of driving the fewest device inputs of the same series?

TTL and ECL families use FET transistor technology.

The______series has become the most widely used CMOS series.

Assume a V_cc of 5 V for the preceding question and determine the average power dissipation, ^PD(ave)^.

CMOS logic families use bipolar transistor technologies.

For standard TTL, a LOW- level input voltage can be:

A______switch acts essentially as a single- pole, single- throw switch controlled by an input logic level.

-Refer to Table 8- 1. Which series has the largest dc noise margin (V_NL)?

Open- collector circuits are especially well suited for high speed switching circuits.

______is ideally suited for applications using battery power or battery backup power.

-Refer to Table 8- 1. Which TTL series has the lowest speed- power product and what are the values of t_D and P_D that produce the product?

Instead of individually soldered ICs in place,______ heats the entire IC and is held in place by a soldered paste.

______TTL allows three possible output states.
