Study Notes
NAND Gate Output
- If all inputs of a NAND gate are true, the output is false.
De Morgan's Laws
- A two-input NAND gate's logic can be expressed as ¬(A ∧ B).
Significance of NAND Gate
- NAND gates play a crucial role in digital systems due to their functional completeness.
ANSI Symbol
- The ANSI symbol for the NAND gate is a distinctive symbol with a diagonal cross.
Functional Completeness
- NAND gates are functionally complete, which means any other logic function can be implemented using only NAND gates.
- Other gates that are functionally complete are NOR gates.
Integrated Circuits
- NAND gates are available as integrated circuits, such as CMOS IC 7400, which includes four independent, two-input, NAND gates.
Boolean Algebra
- The symbol ∧ represents A NAND B in Boolean algebra.
- The symbol ∨ represents A OR B in Boolean algebra.
Transistors
- In TTL ICs using multiple-emitter transistors, a NAND gate requires fewer transistors than a NOR gate.
Logic Gates
- Both NAND and NOR gates are functionally complete, meaning they can be used to create an entire processor alone.
- NAND and NOR gates are the only two gates that are functionally complete, making them crucial in digital systems.
