40 TOP STANDARD LOGIC DEVICES (SLD) Online Quiz – Questions and Answers 1. Ten TTL loads per TTL driver is known as: propagation delay fanout power dissipation noise immunity 2. When an IC has two rows of parallel connecting pins, the device is referred to as: a QFP CMOS a DIP a phase splitter 3. Which digital IC package type makes the most efficient use of printed circuit board space? flat pack SMT TO can DIP 4. The range of a valid LOW input is: 0.4 V to 1.8 V 0.0 V to 0.4 V 0.4 V to 2.4 V 0.4 V to 0.8 V 5. Which of the following summarizes the important features of emitter-coupled logic (ECL)? negative voltage operation, high speed, and high power consumption poor noise immunity, positive supply voltage operation, good low-frequency operation, and low power slow propagation time, high frequency response, low power consumption, and high output voltage swings good noise immunity, negative logic, high frequency capability, low power dissipation, and short propagation time 6. CMOS logic is probably the best all-around circuitry because of its: very high noise immunity low power consumption low power consumption and very high noise immunity packing density 7. The time needed for an output to change as the result of an input change is known as: noise immunity propagation delay fanout rise time 8. What quantities must be compatible when interfacing two different logic families? only the voltages both the voltages and the currents only the currents both the power dissipation and the impedance 9. Low power consumption achieved by CMOS circuits is due to which construction characteristic? small-scale integration DIP packages connecting pads complementary pairs 10.
