Fill in the notes below using the presentation in myPLTW 1.1.6 on Introduction to Logic Gates and Integrated Circuits Component Identification: Digital

Slide 3.What does a transistor allow a small voltage to control ?

What are 2 thiings a transistor can act as?

Slide 4: How many states does a transistor have?

What does a truth table show?

Slide 5: Transistors can be grouped together to form a ____ which is the main component inside an IC.

Slide 6: We will use DIPs. Look up some DIP ICs. What sizes do they come in besides 8 and 14 pin?


Slide 7: What are the inputs in the truth table?

What is the output in the truth table?

How many different outputs are possible with 2 inputs?

Slide 8 What is binary?

If 00 is 0 in binary, and 01 is 1 in binary, what are 2 and 3 in binary (use the values of XY)

Slide 10: what are the 3 ways that ICs are categorized?

Look up how many logic gates are inside each of these kind of ICs:

Slide 11: Complete this table about TTL vs CMOS

constructed from    

Slide 13: Why do we use thte DIP packages for ICs instead of the smaller, higher density chips?

Slides 14-15: Fill in the table about THT vs SMT

How is it attached to the PCB?    

Slide 16: We will use LS chips. What is an advantage of these?

Slide 17: Describe everything you can about an IC with this written on it: SN 74 LS 04 N

Slide 18: Which of these is NOT information on a manufacturer datasheet for an IC?

Slide 19: how many AND gates are on a DM74LS08 chip?

Slide 20: How many pins are on EACH SIDE or a DM74LS08 chip?

Slide 21: Instead of writing 0 and 1 for the logic table, the data sheet uses the letters ___ and ___

Slide 22: What is the maximum low level out put current for a DM74LS08?
