SN74HC00N by Lingxingic

The 74HC00 is a high-speed CMOS quad 2-input NAND gate IC fabricated with silicon gate CMOS technology. It contains four independent NAND gates in a single package. Each gate performs the standard logic NAND function, with the output being high unless both inputs are high. It is a fundamental building block in digital electronics and used widely in logic design.

Key Features

  • Logic Family: HC (High-speed CMOS)

  • Number of Gates: 4 (quad)

  • Inputs per Gate: 2

  • Output Type: CMOS push-pull

  • Voltage Supply Range (Vcc): 2V to 6V

  • Typical Propagation Delay: ~8 ns at Vcc = 5V

  • High Noise Immunity: VIL = 1.5V, VIH = 3.5V at Vcc = 5V

  • Low Power Consumption: Typical ICC < 1 μA

  • Input Compatibility: TTL and CMOS level inputs

  • ESD Protection: Typically 2000V HBM (Human Body Model)

The 74HC00 is a staple of digital design due to its versatility, ease of use, and integration into standard logic systems. As a basic logic building block, it is often used in educational, prototyping, and commercial digital systems.
