NAND
(US) (EU)
Input 1 Input 2 Output
0 x 1
x 0 1
1 1 0
The output value is based on inverting the logical AND of 2
to 5 inputs.
Output is Off when all inputs are On.
NOR
(US) (EU)
Input 1 Input 2 Output
0 0 1
1 x 0
x 1 0
The output value is based on inverting the logical OR of 2
to 5 inputs.
Output is On when all inputs are Off.
XOR
(US) (EU)
Input 1 Input 2 Output
0 0 0
0 1 1
1 0 1
1 1 0
The output value is an exclusive OR of 2 to 5 inputs.
Output is On when only one (exclusive) input is On.
NOT
(US)
(EU)
Input Output
0 1
1 0
Output is the opposite of the input.
RS Flip-Flop
Input 1 (Set)
Input 2 (Reset) Output
0 0 Value remains the same
0 1 0 (Reset)
1 0 1 (Set)
1 1 0 (Reset has priority)
This block is Reset Dominant (Reset has priority if both
inputs are On).
