74ALVC32BQ-Q100X

Overview

The Nexperia 74ALVC32BQ-Q100X is a quad 2-input OR gate from the ALVC family, housed in a DHVQFN-14 (SOT762-1) package. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an ambient temperature range of -40 °C to +125 °C. The device features Schmitt trigger inputs for slow signal tolerance and IOFF circuitry for partial power-down protection. Propagation delay ranges from 1.0 ns to 5.4 ns depending on voltage and temperature.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• IOFF circuitry prevents damaging backflow current during partial power-down
• Schmitt trigger action ensures tolerance for slow input rise and fall times
• DHVQFN package includes side-wettable flanks enabling automatic optical inspection

Applications

• Automotive electronic systems requiring Grade 1 qualification
• Mixed-signal environments utilizing TTL level interfaces
• Partial power-down applications requiring output isolation

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity and packaging variant. Confirm that the DHVQFN-14 package orientation aligns with the PCB footprint design. Ensure the selected component meets the specific AEC-Q100 Grade 1 reliability requirements for the target automotive application environment.

Selection Notes

Select this component when a quad 2-input OR function is required in space-constrained automotive designs. The DHVQFN package offers thermal enhancement and AOI compatibility. Consider the propagation delay specifications relative to system timing requirements across the full operating voltage and temperature range.

Part Context

This part belongs to the 74ALVC32-Q100 series of automotive-grade logic gates. The 'BQ' designation specifically identifies the DHVQFN-14 leadless package variant. It shares functional characteristics with other packages in the series but differs in physical dimensions and thermal properties suitable for high-density mounting.

Replacement Considerations

Direct replacements include other 74ALVC32-Q100 variants such as the SO14 or TSSOP14 packages if form factor changes are acceptable. Cross-family substitutes like 74LVC32-Q100 may require verification of speed and voltage compatibility.
