74HCT2G02DP-Q100H

Overview

The Nexperia 74HCT2G02DP-Q100H is a dual 2-input NOR gate from the 74HCT2G02-Q100 series, qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features TTL input levels, CMOS low power dissipation, and high noise immunity. It is housed in an SOT505-2 (TSSOP8) package with 8 leads.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Wide operating temperature range specified from -40 °C to +125 °C
• High noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• ESD protection compliant with ANSI/ESDA/JEDEC JS-001 class 2 and JS-002 class C3

Applications

• Automotive electronic systems requiring NOR logic functions
• Interfaces between TTL logic levels and CMOS circuits
• General-purpose digital logic applications in harsh environments

Procurement Notes

Verify the specific ordering suffix DP corresponds to the TSSOP8 package when sourcing. Confirm that the H suffix indicates halogen-free status as per Nexperia definitions. Ensure compatibility with AEC-Q100 Grade 1 requirements for your target application environment. Check the most recent datasheet revision for any updates to electrical characteristics or marking codes before finalizing design specifications.

Selection Notes

Select this component when a dual 2-input NOR gate with TTL-compatible inputs is required in a compact surface-mount package. The HCT series ensures compatibility with standard TTL logic outputs while offering CMOS power benefits. Consider the TSSOP8 package dimensions if board space is constrained. Verify that the 4.5 V to 5.5 V supply voltage range aligns with your system's power rails.

Part Context

This part belongs to the 74HCT2G02-Q100 family of dual 2-input NOR gates manufactured by Nexperia. The family includes HC and HCT variants, with the HCT version specifically designed for TTL input level interfacing. All members are automotive-qualified and share similar functional characteristics but differ in input threshold voltages and supply voltage ranges.

Replacement Considerations

Direct substitutes include other 74HCT2G02-Q100 variants with different packages, such as 74HCT2G02DC-Q100H (VSSOP8). Cross-vendor equivalents must match the dual 2-input NOR function, TSSOP8 package, and AEC-Q100 Grade 1 qualification.
