74AHC2G32DC-Q100H

Overview

The Nexperia 74AHC2G32DC-Q100H is a dual 2-input OR gate qualified to AEC-Q100 Grade 1 for automotive use. It operates on a supply voltage range of 2.0 V to 5.5 V with overvoltage tolerant inputs up to 5.5 V. The device features CMOS low power dissipation, symmetrical output impedance, and high noise immunity. It supports an ambient temperature range from -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Latch-up performance exceeds 100 mA per JESD 78 Class II Level A.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Overvoltage tolerant inputs enabling operation as translators in mixed voltage environments
• High noise immunity and balanced propagation delays

Applications

• Automotive electronic systems requiring Grade 1 component qualification
• Mixed voltage logic translation between different signal domains
• General purpose digital logic processing in harsh thermal environments

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's current ordering information to confirm packaging configuration. Ensure the design accounts for the VSSOP8 package dimensions and thermal derating characteristics specified in the datasheet. Confirm that the application environment remains within the recommended operating conditions for voltage and temperature ranges.

Selection Notes

Select this component when automotive reliability under AEC-Q100 Grade 1 is required alongside dual OR gate functionality. The wide supply voltage range and input tolerance make it suitable for interfacing between 2.0 V and 5.5 V logic domains. Consider the VSSOP8 package constraints if board space is limited compared to larger packages.

Part Context

This part belongs to the Nexperia 74AHC_AHCT2G32-Q100 family of dual 2-input OR gates. The DC variant utilizes the SOT765-1 (VSSOP8) plastic very thin shrink small outline package. It is distinct from the DP variant which uses the TSSOP8 package. The product data sheet revision 4 provides the definitive specifications for this component.

Replacement Considerations

The 74AHCT2G32DC-Q100H serves as the TTL-level input compatible alternative within the same package and qualification standard.
