IC GATE NAND 4CH 2-INP 14DIP
The 74HC00N is a quad 2-input NAND gate IC from NXP USA Inc. It is a 14-pin DIP (dual in-line package) device. The 74HC00N is a high-speed CMOS logic device. It has four independent 2-input NAND gates, each of which performs the logic NAND function. The output is high when both inputs are low. The 74HC00N is used in a variety of applications, including logic level conversion, signal buffering, and signal conditioning. It can also be used to create complex logic functions such as counters, flip-flops, and shift registers. It is also used in digital circuits such as microprocessors, microcontrollers, and embedded systems. (For reference only)
