Logic Devices

Commonly used logic devices include:

• AND Gate: Outputs HIGH only when all inputs are HIGH.
• OR Gate: Outputs HIGH when any input is HIGH.
• NOT Gate (Inverter): Inverts the input signal.
• NAND Gate: AND followed by NOT; outputs LOW only when all inputs are HIGH.
• NOR Gate: OR followed by NOT; outputs LOW when any input is HIGH.
• XOR Gate: Outputs HIGH when inputs are different.
• XNOR Gate: Outputs HIGH when inputs are the same.

Common ICs: 74HC00 (NAND), 74HC02 (NOR), 74HC04 (NOT), 74HC08 (AND), 74HC32 (OR), 74HC86 (XOR).
