74HCT03D-Q100J

Overview

The Nexperia 74HCT03D-Q100J is a quad 2-input NAND gate with open-drain outputs, qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40 °C to +125 °C. The device features TTL input levels, high noise immunity, and ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Propagation delay is typically 24 ns at 4.5 V with 50 pF load.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Open-drain output configuration enabling wired-AND logic applications
• TTL-compatible input levels ensuring interface compatibility
• Robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Applications

• Automotive electronic control units
• General-purpose digital logic processing
• Signal buffering in mixed-voltage systems

Procurement Notes

Verify the specific suffix 'J' against the manufacturer's current ordering information to confirm packaging details such as tape and reel specifications. Confirm that the SO14 package variant matches the required footprint for the target PCB design. Ensure compliance with RoHS directives and check for any recent product change notices affecting availability or material composition.

Selection Notes

Select this component when an open-drain NAND function is required in automotive environments. The HCT series ensures compatibility with TTL logic families while offering CMOS low power dissipation. Consider the wide operating temperature range and high noise immunity for harsh industrial or vehicular settings where signal integrity is critical.

Part Context

This part belongs to the Nexperia 74HCT03-Q100 family, which includes HC and HCT variants. The HCT version specifically targets TTL-level inputs. The 'D' indicates the SO14 plastic small outline package, while 'Q100' denotes automotive qualification. This family provides robust digital logic solutions designed for reliability in demanding applications.

Replacement Considerations

Check for direct equivalents like the 74HC03D-Q100 if CMOS inputs are acceptable. Verify pinout compatibility with other quad NAND gates in the 74xx series. Ensure any substitute maintains the open-drain output characteristic and meets the same AEC-Q100 Grade 1 requirements.
