74VHC02N

Inverter Gates Overview

The Fairchild Semiconductor 74VHC02N is a quad 2-input NOR gate integrated circuit belonging to the advanced high-speed CMOS (VHC) logic family. It operates within a supply voltage range of 2.0V to 5.5V and features low power dissipation with high noise immunity. The device utilizes silicon gate CMOS technology to achieve propagation delays comparable to equivalent Bipolar Schottky TTL while maintaining low static current consumption. It includes input protection circuits that allow operation with voltages exceeding VCC, providing power-down protection and facilitating level shifting between different logic families.

Inverter Gates Feature Summary

• Advanced high-speed CMOS technology provides performance similar to Bipolar Schottky TTL with low power consumption
• High noise immunity with minimum noise margins defined as a percentage of supply voltage
• Input protection circuits enable tolerance for voltages beyond the supply rail, supporting power-down protection
• Pin and function compatible with standard 74HC series devices

Inverter Gates Applications

• General-purpose digital logic control in consumer electronics
• Signal processing in industrial automation systems
• Interface circuits requiring level translation between 3.3V and 5V logic domains
• Battery-powered equipment utilizing low-power logic gates

Inverter Gates Procurement Notes

Verify the specific package configuration and suffix codes against official Fairchild or onsemi datasheets, as packaging variations exist. Confirm RoHS compliance status for the specific manufacturing lot, as older production runs may differ from current standards. Ensure the source document explicitly identifies the component as the 74VHC02N variant rather than other members of the 74VHC family. Cross-reference pinouts to guarantee compatibility with existing PCB footprints before procurement.

Inverter Gates Selection Notes

Select this component when design requirements demand high switching speeds combined with low static power consumption. It is suitable for applications requiring robust noise immunity in electrically noisy environments. The wide operating voltage range allows flexibility in system design involving mixed voltage levels. Verify that the through-hole DIP package meets mechanical constraints and that the input protection features align with the expected signal integrity requirements of the target application.

Inverter Gates Part Context

The 74VHC02N is part of the broader 74VHC logic family, which represents an evolution of the standard 74HC series. This family bridges the performance gap between standard CMOS and faster bipolar technologies. The 'VHC' designation indicates Advanced High-Speed CMOS characteristics. As a member of the 74-series, it maintains functional compatibility with legacy designs while offering improved electrical specifications such as lower propagation delay and higher drive capability compared to earlier generations.
