74AHC1G02GW-Q100H

Overview

The Nexperia 74AHC1G02GW-Q100H is a single 2-input NOR gate from the AHC logic family, housed in a TSSOP5 (SOT353-1) package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, symmetrical output impedance, and balanced propagation delays. Static characteristics include low input leakage current and high noise immunity. Dynamic performance specifies typical propagation delays ranging from 3.2 ns to 6.3 ns depending on load capacitance and voltage.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards for automotive applications
• Overvoltage tolerant inputs allowing use as translators in mixed voltage environments
• High noise immunity with CMOS low power dissipation characteristics
• ESD protection exceeding 2000 V per Human Body Model and 1000 V per Charged Device Model

Applications

• Automotive electronic systems requiring qualified logic components
• Mixed voltage signal translation between different logic levels
• General purpose digital logic processing in consumer electronics

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets the AEC-Q100 Grade 1 qualification requirements for your target application environment. Ensure input voltage levels remain within the specified tolerance limits to prevent damage. Check the most recent datasheet revision for any updates to electrical characteristics or marking codes before finalizing procurement specifications.

Selection Notes

Select this component when a single 2-input NOR function is required in a compact surface-mount package. The AHC series offers faster switching speeds compared to standard HC devices while maintaining CMOS power efficiency. The wide supply voltage range provides flexibility for various system architectures. Consider the TSSOP5 footprint constraints and thermal dissipation capabilities during PCB layout design.

Part Context

This part belongs to the Nexperia 74AHC1G02-Q100 family of single 2-input NOR gates. Other variants in the family include the GV package (SC-74A/SOT753) and GZ package (XSON5/SOT8065-1). The AHCT variant shares similar functionality but utilizes TTL-compatible input levels instead of CMOS levels. All variants maintain the same core logical operations and automotive qualification status.

Replacement Considerations

Direct pin-to-pin replacements within the same family include the 74AHC1G02GV-Q100H (SC-74A package) and 74AHC1G02GZ-Q100H (XSON5 package). Verify that alternative packages meet the physical space and thermal requirements of the existing design. Ensure that any substitute component maintains the AEC-Q100 Grade 1 qualification if used in automotive contexts.
