7404 DIP Hex Inverter Logic NOT Gate

• The chip is basically used where a logic inverter is needed.
• Inverter Gates in this chip provide output which is negated logic input.
• The chip has six gates which do NOT operation.
• Inverting NOT gates are single input device.
• They have an output level that is normally at logic level 1 and goes LOW to a logic level 0 when its single input is at logic level 1.
• In other words, it inverts (complements) its input signal.
• The output from a NOT gate only returns HIGH  when its input is at logic level 0.

Boolean expression:

•  A = Q
