Logic Gates
Output is only on if both inputs are on
AND Gate
Basic building block of counters and shift registers
Flip Flop or Latch
Uses only 1s and 0s
Binary
Used to turn a circuit on or off
Switch
If I need a light to turn on when 2 switches are turned on, what gate do I need?
AND
Inverts the signal
NOT gate
A signal that repeats on and off in a fixed interval
Clock
Uses 0-9
Decimal
Wires or Jumpers
NAND
Has output when only 1 input is on. If both are on or off the output is off.
XOR gate
Used to remember how many times a 1 signal has been received.
Counter
Base 16
Hexidecimal
Black chips used on breadboards
ICs (Integrated Circuits)
0 or Low
The opposite of an AND gate.
NAND Gate
Used to move data from one location to another
Shift Register
Contains only 8 numbers
Octal
What does LED stand for?
Light Emitting Diode
How many 2 input AND gates would I need to have 1 output with 4 inputs?
3
Has output only if both inputs are off or on. If one input is on, there is no output.
XNOR
Used to store information
Memory
0011 converted to decimal
3
When something is off, is it a 0 or a 1 signal?
0
If a NOT gate was connected to the output of an AND gate, what kind of gate would I have?
NAND
