Combinational Logic/Universal LogicCircuits Flashcards
Combinational logic is the combination of _____.
Combinational logic is the combining of two or more logic gates.
What function is available at pin 7 with HIGH signals applied to pins 1 and 2?

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.

The OR function is available at pin 10, while the NOR function is available at pin 9.
With a HIGH signal applied to pin 3, which pin has the buffer function available?

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.

Enter the correct logic levels for the outputs of gates A thru D.


The ____ and ____ gates are commonly used as universal logic gates.

The NAND and NOR gates are commonly used as universal logic gates.
An IC called QUAD NAND is made by combining _____ on a single IC (Integrated Circuit). Similarly, an IC called QUAD NOR is made by combining _______ on a single IC.

An IC called QUAD NAND is made by combining 4 NAND gates on a single IC. Similarly, an IC called QUAD NOR is made by combining 4 NOR gates on a single IC.
The ______ uses 4 NAND gates to produce the other logic functions.

The QUAD NAND uses 4 NAND gates to produce the other logic functions.

If the inputs to a NAND gate are connected, the output produces the ______.

If the inputs to a NAND gate are connected, the output produces the NOT function.
When two NAND gates are connected, the output produces the _____function.

When two NAND gates are connected, the output produces the AND function.
The_____ is produced with 5 NAND gates. Two ____ ICs must be used.

The XOR function is produced with 5 NAND gates. Two QUAD NAND ICs must be used.
