Here is the answer key
to November's puzzle:
LASER DISC OPTICS
IN
70. Why are integrated circuits divided into two categories ( digital and linear)?
a. These names refer to two general types of packages.
b. These are the two temperature ranges or grades into which ICs are
classified by testing.
c. I Cs are simply circuits that happen to be constructed integrally, and like all
circuits, are either switching-type or amplifying-type.
d One type processes infonnation and the other controls large working
devices such as motors.
e. ICs are used for either input purposes or output purposes.
71. What advantages do I Cs have over discrete-device circuits due to their greater
complexity (more circuitry in less area)?
a. Smaller size
b. Higher reliability
c. Better overall perfonnance
d Lower cost
e. All but c above
72. What are the limitations of integrated circuits?
a. Not all electronic components can be efficiently integrated into a silicon
chip.
b. ICs are generally more expensive than their discrete-device counterparts.
c. ICs are limited to rather low voltages.
d ICs can stand a relatively small amount of power dissipation (heating).
e. All but b above.
73. Which of the following common electronic components is not found in
ordinary ICs?
1. Inductors
b. Diodes
c. Resistors
d Transistors
e. Low-capacitance capacitors
74. Why is the plastic dual-in-line package the most popular IC package?
a. It is low in cost.
b. It is easy to insert and solder into printed wiring boards by means of
automatic handling equipment.
c. Its solid construction makes it ruggedly resist vibration and impact.
d It is one of the smallest possible packages.
e. All but d above.
