Combinational Logic/Universal LogicCircuits Flashcards
Combinational logic is the combination of _____.
Combinational logic is the combining of two or more logic gates.

NAND
Two HIGHs applied to an AND gate produce a HIGH output. If the output is applied to a NOT gate, the final output is a NAND function.

Pin 8
The output at pin 10 bypasses all gates. The signal is the same as the signal applied at pin 3.
The output at pin 9 passes through an inverter. The NOT function is available at pin 9.
