74AHC32BQ-Q100X

Overview

The Nexperia 74AHC32BQ-Q100X 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 ambient temperatures from -40 °C to +125 °C. The device features CMOS input levels, balanced propagation delays, and Schmitt-trigger action on all inputs. It utilizes the DHVQFN14 (SOT762-1) package with side-wettable flanks.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Overvoltage tolerant inputs allowing operation up to 5.5 V
• Schmitt-trigger action on all inputs for improved noise immunity
• DHVQFN package with side-wettable flanks enabling automatic optical inspection

Applications

• Automotive electronic systems requiring high reliability
• Mixed voltage environments utilizing overvoltage tolerant inputs
• Digital logic circuits requiring quad 2-input OR functionality

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm that the DHVQFN14 package variant aligns with the intended PCB footprint and thermal management requirements. Ensure the component meets the specified AEC-Q100 Grade 1 qualification for the target automotive application environment.

Selection Notes

Select this component when an automotive-grade OR gate is required with wide supply voltage flexibility. The DHVQFN14 package offers a compact solution suitable for space-constrained designs. Verify compatibility with system voltage levels, as this variant specifies CMOS input thresholds rather than TTL levels.

Part Context

This part belongs to the Nexperia 74AHC32-Q100 family of quad 2-input OR gates. It shares functional characteristics with other members of the series but is distinguished by its specific DHVQFN14 packaging and automotive qualification status. The BQ suffix indicates the leadless thermal enhanced very thin quad flat package configuration.

Replacement Considerations

Direct substitutes include other 74AHC32 variants in different packages such as SO14 or TSSOP14, provided pinout compatibility is maintained. Cross-family replacements require verification of input/output voltage thresholds and propagation delay specifications against original design constraints.
