7404 74ls04 74hc04 Hex Inverter Ic
The 7404 / 74LS04 / 74HC04 Hex Inverter IC is a widely used digital logic component that features six independent NOT gates, also known as inverters. Each inverter inverts the input logic level (0 to 1, or 1 to 0), enabling it to serve as a core component in digital logic systems, waveform generators, timing circuits, and microcontroller projects.
Available in both 74LS (Low Power Schottky TTL) and 74HC (High-Speed CMOS) variants, this IC supports a variety of voltage levels, making it suitable for interfacing between TTL and CMOS systems. Whether you’re designing with microcontrollers like PIC16F887 or ATmega328P, or working on low-level hardware signal control, the 7404 IC provides fast and reliable logic inversion.
Use it in waveform shaping, logic condition checking, or to implement simple oscillators using resistor-capacitor (RC) networks. For prototyping and DIY electronics, the 7404 IC is an essential and cost-effective choice.
