Working Principles

The SN74AHCT02DG4 is based on CMOS (Complementary Metal-Oxide-Semiconductor) technology. It consists of four independent 2-input NOR gates that perform logical NOR operation on their respective inputs. The output of each gate is an open-drain configuration, which means it can either be pulled low or left floating. When the inputs are at a logic high level, the output is pulled low, and when any input is at a logic low level, the output is left floating.

Detailed Application Field Plans

The SN74AHCT02DG4 is commonly used in various digital systems where logical NOR operation is required. Some typical application fields include:

1. Digital signal processing
2. Microcontrollers and microprocessors
3. Communication systems
4. Industrial automation
5. Automotive electronics
