7404 IC – Hex Inverter (NOT Gate) DIP-14
🔲 7404 IC – Hex Inverter (NOT Gate) DIP-14
The 7404 IC is a digital logic chip containing six independent NOT gates (inverters). Each inverter performs the basic logic NOT function, inverting the input signal (HIGH to LOW, or LOW to HIGH). Housed in a 14-pin Dual Inline Package (DIP), it’s widely used in digital electronics, signal conditioning, and microcontroller circuits.
