74AHCT32BQ-Q100X

Overview

The Nexperia 74AHCT32BQ-Q100X is a quad 2-input OR gate from the 74AHCT series, qualified to AEC-Q100 Grade 1 for automotive use. It operates on a supply voltage of 4.5 V to 5.5 V with TTL input levels. The device features Schmitt-trigger inputs and overvoltage tolerance up to 5.5 V. Propagation delay ranges from 6.9 ns to 9.0 ns at CL=15 pF and 50 pF respectively. Power dissipation capacitance is 12 pF. It is housed in a DHVQFN14 (SOT762-1) package.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• TTL-compatible input levels for direct interface with legacy logic
• Schmitt-trigger action ensures noise immunity and tolerance for slow rise/fall times
• DHVQFN package includes side-wettable flanks enabling automatic optical inspection

Applications

• Automotive electronic systems requiring robust logic gating
• Mixed-voltage environments utilizing TTL-to-CMOS translation
• Signal conditioning circuits requiring noise filtering via Schmitt triggers

Procurement Notes

Verify the specific suffix 'X' indicates reel packaging when ordering. Confirm the BQ variant corresponds to the DHVQFN14 package type SOT762-1. Ensure the AHCT designation matches the required 4.5 V to 5.5 V operating range and TTL input thresholds rather than CMOS levels found in the AHC variant. Cross-reference the AEC-Q100 Grade 1 requirement against system specifications.

Selection Notes

Select this component when TTL-level compatibility is mandatory within a 5 V system. The AHCT series provides balanced propagation delays suitable for general-purpose logic applications. The DHVQFN package offers thermal enhancement and compact footprint advantages for space-constrained designs. Verify that the 5.5 V overvoltage tolerance meets the input signal requirements of interfacing components.

Part Context

This part belongs to the Nexperia 74AHC_AHCT32-Q100 family of quad 2-input OR gates. The family includes variants with different input logic families (AHC for CMOS, AHCT for TTL) and package options including SO14, TSSOP14, and DHVQFN14. All variants share the same functional logic and automotive qualification status.

Replacement Considerations

Direct substitutes include other 74AHCT32 parts from Nexperia in different packages such as 74AHCT32D-Q100 or 74AHCT32PW-Q100. Generic equivalents must match the 74AHCT logic family, 14-pin configuration, and automotive grade requirements.
