74HCT32BQ-Q100,115

Overview

The 74HCT32BQ-Q100,115 is a quad 2-input OR gate from the 74HCT series, manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features TTL input levels and includes clamp diodes on inputs for overvoltage interfacing. It is housed in a DHVQFN14 package (SOT762-1) with side-wettable flanks. Qualified to AEC-Q100 Grade 1 standards, it offers high noise immunity and ESD protection exceeding 2000 V (HBM).

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards.
• TTL-compatible input logic levels for direct interface with TTL devices.
• DHVQFN package design with side-wettable flanks enabling automated optical inspection.
• High electrostatic discharge protection performance per JEDEC standards.

Applications

• Automotive electronic systems requiring robust logic gating.
• Industrial control circuits operating in harsh thermal environments.
• Signal routing and logic combination in mixed-voltage digital interfaces.

Procurement Notes

Verify that the ordering suffix matches the specific DHVQFN14 package configuration. Confirm the HCT logic family designation ensures compatibility with TTL-level signal sources. Check the AEC-Q100 Grade 1 qualification status if automotive reliability is required. Ensure the component meets the specified -40 °C to +125 °C operating temperature range for the intended application environment.

Selection Notes

Select this component when TTL input thresholds are necessary within a CMOS logic framework. The DHVQFN14 package is suitable for applications demanding compact PCB footprints and reliable solder joint inspection via AOI. Consider the 4.5 V to 5.5 V supply voltage constraint during power budgeting. Evaluate the propagation delay characteristics against system timing requirements at the target operating voltage.

Part Context

This part belongs to the 74HCT32-Q100 family of quad 2-input OR gates. It shares functional specifications with other packages in the series, such as SO14 and TSSOP14, but differs in physical dimensions and thermal properties due to the leadless DHVQFN form factor. The 'BQ' suffix specifically denotes the DHVQFN14 variant with side-wettable flanks.

Replacement Considerations

Direct pin-to-pin replacements include other 74HCT32 variants in different packages, such as 74HCT32D-Q100 or 74HCT32PW-Q100, provided the package footprint is adapted. Verify that any substitute maintains the same AEC-Q100 Grade 1 qualification and DHVQFN14 package type if space constraints persist.
