74AHC32D-Q100J

Overview

The Nexperia 74AHC32D-Q100J is a quad 2-input OR gate qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 2.0 V to 5.5 V and supports temperatures from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, Schmitt-trigger action on all inputs, and balanced propagation delays. Static characteristics include low power dissipation and high noise immunity. Dynamic performance at 5.0 V with 50 pF load shows typical propagation delay of 4.1 ns and maximum of 9.5 ns across the full temperature range.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Overvoltage tolerant inputs enabling operation in mixed voltage environments
• Schmitt-trigger action on all inputs for improved noise immunity
• Balanced propagation delays with CMOS low power dissipation

Applications

• Automotive logic circuits requiring robust signal processing
• Mixed voltage translation between different logic domains
• High noise immunity digital signal routing

Procurement Notes

Verify the specific suffix 'J' against the manufacturer's current ordering information to confirm package type and tape/reel specifications. Ensure the design accounts for the SO14 (SOT108-1) package thermal derating requirements above 100 °C. Confirm that the application environment remains within the specified -40 °C to +125 °C operating temperature range for guaranteed performance.

Selection Notes

Select this component when an automotive-grade quad OR gate is required with wide supply voltage flexibility. The 74AHC variant is suitable for CMOS input levels, whereas the 74AHCT variant supports TTL levels. Consider the SO14 package if leaded surface-mount assembly is preferred. Verify input transition rates do not exceed 20 ns/V at higher supply voltages to ensure proper switching behavior.

Part Context

This part belongs to the Nexperia 74AHC32-Q100 family of quad 2-input OR gates designed for automotive applications. It shares functional similarities with other members of the 74AHC series but is distinguished by its AEC-Q100 qualification and specific SO14 packaging. The device provides a standard OR logic function with enhanced reliability features for harsh environments.

Replacement Considerations

Direct substitutes include the 74AHCT32D-Q100J for TTL-compatible inputs. Other manufacturers may offer equivalent quad OR gates, but verification of AEC-Q100 compliance and pinout compatibility is essential before substitution.
