74HCT2G00DP-Q100H

Overview

The Nexperia 74HCT2G00DP-Q100H is a dual 2-input NAND gate from the 74HCT series, designed for automotive applications. 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 utilizes TSSOP8 (SOT505-2) packaging with eight leads. It features TTL input switching levels, symmetrical output impedance, and high noise immunity. Static characteristics include low power dissipation and ESD protection exceeding 2000 V (HBM Class 2). Dynamic performance at 4.5 V includes a typical propagation delay of 12 ns and transition time of 6 ns.

Feature Summary

• Qualified to AEC-Q100 Grade 1 standards for automotive use
• Features CMOS low power dissipation and balanced propagation delays
• Includes clamp diodes on inputs for interface flexibility
• Provides high noise immunity and symmetrical output impedance

Applications

• Automotive electronic systems requiring Grade 1 qualification
• Digital logic circuits utilizing TTL-compatible inputs
• Signal processing in environments with high electromagnetic interference

Procurement Notes

Verify that the specific part number suffix matches the required package type and temperature grade. Confirm compliance with RoHS and REACH regulations as specified in the chemical content documentation. Ensure design safeguards are implemented to prevent operation beyond absolute maximum ratings, particularly regarding supply voltage and current limits. Cross-reference marking codes to validate authenticity upon receipt.

Selection Notes

Select this component when TTL-level compatibility is required alongside automotive reliability standards. The HCT variant ensures direct interfacing with standard TTL logic families without additional level shifting. Consider the TSSOP8 package for space-constrained PCB layouts while maintaining thermal performance within the extended industrial temperature range.

Part Context

This device belongs to the Nexperia 74HCT2G00-Q100 family of dual 2-input NAND gates. It shares functional similarities with the 74HC2G00-Q100 but differs in input voltage thresholds, adhering to TTL specifications rather than CMOS levels. Both variants share identical pinouts and packaging options, facilitating potential design swaps where voltage compatibility allows.

Replacement Considerations

Direct substitutes include the 74HC2G00DP-Q100H, provided the application can accommodate CMOS input levels instead of TTL. Other compatible devices within the same automotive-grade logic family may be considered if pinout and electrical characteristics align with system requirements.
