Q.1.

One output structure of a TTL gate is often referred to as a ________.

Q.2.

Which equation is correct?

Q.3.

Which is not part of emitter-coupled logic (ECL)?

Q.4.

A certain gate draws 1.8 A when its output is HIGH and 3.3 µA when its output is LOW. VCC is 5 V and the gate is operated on a 50% duty cycle. What is the average power dissipation (PD)?

Q.5.

The greater the propagation delay, the ________.

Q.6.

A pull-down resistor must be used with open-collector TTL circuits.

Q.7.

The speed-power product provides a basis for the comparison of logic circuits when power dissipation and propagation delay are important considerations in the selection of the type of logic to be used.

Q.8.

Metal-oxide semiconductor field-effect transistors (MOSFETs) are the active switching elements in CMOS circuits.

Q.9.

There are four different logic level ranges for TTL and CMOS: VIL, VIH, VOL, and VOH.

Q.10.

ECL IC technology is faster than TTL technology.

Q.11.

Power dissipation is a measure of a circuit's noise immunity.

Q.12.

The total sink current decreases with an increase in each load gate input.

Q.13.

CMOS is a more dominant IC technology than TTL.

Q.14.

Unused TTL inputs should be tied LOW.

Q.15.

The greater the propagation delay, the higher the maximum frequency.
