74HC05BQ-Q100,115

Overview

The 74HC05BQ-Q100,115 is a hex inverter with open-drain outputs from the Nexperia 74HC05-Q100 automotive logic family. It operates within a supply voltage range of 2.0 V to 6.0 V and complies with JEDEC standard no. 7A. The device features CMOS input levels and latch-up performance exceeding 100 mA per JESD 78 Class II level A. It is qualified to AEC-Q100 Grade 1 standards for automotive use. Operating temperatures are specified from -40 °C to +85 °C and up to +125 °C. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). The component utilizes a DHVQFN14 package (SOT762-1) measuring 2.5 × 3 × 0.85 mm.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Open-drain output configuration enabling active-LOW wired-OR or active-HIGH wired-AND functions
• Wide operating voltage range supporting 2.0 V to 6.0 V applications
• DHVQFN package with side-wettable flanks facilitating automatic optical inspection

Applications

• Automotive electronic systems requiring robust logic inversion
• Mixed-voltage environments utilizing open-drain bus architectures
• Industrial control circuits demanding high noise immunity and latch-up resistance

Procurement Notes

Verify that the specific ordering suffix matches the required DHVQFN14 package variant. Confirm the temperature grade aligns with the intended operational environment limits. Ensure design specifications account for the mandatory external pull-up resistors required for proper open-drain functionality. Cross-reference the latest datasheet revision to validate current electrical characteristics before finalizing procurement.

Selection Notes

Select this component when an automotive-grade hex inverter with open-drain outputs is required. The wide voltage range supports diverse power supply configurations. The compact leadless package optimizes PCB space. Verify compatibility with existing system voltage levels and ensure adequate thermal management strategies are implemented for the selected ambient temperature range.

Part Context

This part belongs to the Nexperia 74HC05-Q100 series, which provides hex inverters with open-drain outputs. The series includes multiple package options such as SO14 and TSSOP14. All variants share identical electrical characteristics but differ in physical footprint and mounting style. The Q100 designation indicates compliance with automotive reliability standards.

Replacement Considerations

Direct substitutes include other 74HC05-Q100 variants with different packages, such as 74HC05D-Q100 or 74HC05PW-Q100. Verify pinout compatibility and package dimensions before substitution. Non-Q100 versions lack automotive qualification and should not be used if AEC-Q100 compliance is mandatory.
