Overview
The 74HC02D is a high-speed CMOS 2-input NOR gate integrated circuit produced by Toshiba Semiconductor and Storage. This component is fabricated using silicon gate C2MOS technology, which combines the high speed of LSTTL (Low-power Schottky Transistor-Transistor Logic) with the low power dissipation characteristics of CMOS (Complementary Metal-Oxide-Semiconductor) technology. The 74HC02D is designed to provide four independent 2-input NOR gates, making it suitable for a wide range of digital logic applications.
