DIP
Dual Inline Package
SOIC
Small Outline Integrated Circuit
PLCC
Plastic Leaded chip carrier
Another name for truth table
Logic Table, Function Table
Truth Table
A list of all possible input values to a digital circuit in binary order with the output response for each input combination
Another way to say “Low”
off or L or 0
Another way to say “High”
on or H or 1
Integrated Chip (IC)
An electronic circuit that has transistors, diodes, resistors, and capacitors in a single package
Components to make an integrated circuit
Transistors –> Gates –? Integrated circuit
All logic gates are available as an ________
Integrated Circuit (IC)
Transistor-Transistor Logic (TTL) is constructed from a _____
Bipolar junction Transistors (BJT)
Advantages & Disadvantages of a Transistor-Transistor Logic (TTL)
+Faster than CMOS
+Not sensitive to damage from electrostatic-discharge
- Uses more power than CMOS
A Complementary Metal Oxide Semiconductor (CMOS) is constructed from a _____
Metal Oxide Semiconductor Field-Effect Transistors (MOSFET)
Advantages & Disadvantages of a A Complementary Metal Oxide Semiconductor (CMOS)
+ Uses less power than TTL
- Slower than TTL
- Very sensitive to damage from electrostatic-discharge
Analog Signal
- Continuous value reporting
- Infinite range of values
- More precise than Digital, but more difficult to work with
Ex: radio waves
Parts of Analog
- Amps (peak)
- Amps (peak-peak)
- Period (T)
- Frequency (f)
Analog Waves
- SIne Wave
- Square Wave (only when it changes direction + to -)
- Random - Periodic
Digital Signal
- Commonly referred to as square wave/clock signals
- Minimum - 0V
- Maximum - 5V
Parts of Digital
1.Amps
2. Period (T)
3. Time High (tH)
4. Time Low (tL)
5. Falling Edge
6. Rising Edge
7. Frequency (f)
8. Duty Cycle (%)
Digital Wave Type
Square Wave
Period (T)
the time (sec) it takes for ONE CYCLE to repeat itself
Frequency (f)
how many cycles in 1 second (base unit)
f = 1/T = ____Hz
Duty Cycle
DC = (tH/T) x 100 = _____%
* the answer has to be less than 100 for it to make sence since it is a % answer
