Overview
The 74HC03D is a high-speed CMOS 2-input NAND gate integrated circuit produced by Toshiba Semiconductor and Storage. It is fabricated using silicon gate C2MOS technology, which allows for high-speed operation similar to equivalent LSTTL while maintaining the low power dissipation characteristic of CMOS devices. This quad 2-input NAND gate features open-drain outputs, making it suitable for various applications such as wired-AND logic, LED drivers, and other high-current load driving scenarios.
