74HC2G02DP-Q100H

Overview

The Nexperia 74HC2G02DP-Q100H is a dual 2-input NOR gate from the 74HC(Q100) series, housed in an SOT505-2 (TSSOP8) package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS input levels, high noise immunity, and low power dissipation. It complies with AEC-Q100 Grade 1 standards for automotive applications and includes clamp diodes on inputs.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Wide operating temperature range spanning -40 °C to +125 °C
• CMOS logic input levels with high noise immunity characteristics

Applications

• Automotive electronic systems requiring Grade 1 component qualification
• General-purpose digital logic circuits utilizing NOR functionality
• Interfaces requiring current limiting resistors via input clamp diodes

Procurement Notes

Verify the specific ordering suffix DP corresponds to the TSSOP8 package configuration required for your design. Confirm that the HC logic family meets your system's voltage and speed requirements compared to HCT alternatives. Ensure compliance with AEC-Q100 Grade 1 specifications if deploying in automotive environments. Cross-reference marking codes H02 against assembly documentation.

Selection Notes

Select this component when a dual NOR gate is required in a compact TSSOP8 footprint. The HC series provides standard CMOS input thresholds suitable for 2.0 V to 6.0 V operation. Consider the HCT variant if TTL-level interfacing is necessary instead of pure CMOS levels. Evaluate the thermal derating characteristics above 96 °C for total power dissipation limits during layout.

Part Context

This part belongs to the Nexperia 74HC(Q100) family of dual 2-input NOR gates. It shares functional similarities with other devices in the series but differs in package type and logic threshold characteristics. The Q100 designation indicates automotive-grade reliability testing, distinguishing it from standard commercial variants while maintaining identical logical operations.

Replacement Considerations

The 74HCT2G02DP-Q100H serves as a direct pin-compatible alternative within the same package offering TTL-level input thresholds. Other dual NOR gates from the 74HC or 74HCT families may be considered if package constraints allow.
