74HCT04DB-Q100J

Overview

The Nexperia 74HCT04DB-Q100J is a hex inverter integrated circuit designed for automotive applications, qualified to AEC-Q100 Grade 1 standards. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL input levels, high noise immunity, and low power dissipation. It includes clamp diodes on inputs to allow interfacing with voltages exceeding VCC using current limiting resistors. The component is housed in a SO14 plastic small outline package (SOT108-1) with 14 leads.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• TTL input levels compatible with standard logic families
• High noise immunity and CMOS low power dissipation characteristics
• Latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Applications

• Automotive electronic systems requiring robust logic inversion
• Signal conditioning circuits utilizing TTL level compatibility
• Designs necessitating operation across extended industrial temperature ranges

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct package type and temperature grade. Confirm that the requested variant matches the required AEC-Q100 qualification status for your target application. Cross-reference the datasheet revision history to ensure all recent updates regarding ESD specifications and package outlines are accounted for during design integration.

Selection Notes

Select this component when TTL input thresholds are required within a wide supply voltage environment. Ensure the design accommodates the specified propagation delay and transition times under expected load capacitance conditions. Verify that the thermal management strategy aligns with the total power dissipation derating curves provided for the SO14 package at maximum operating temperatures.

Part Context

This part belongs to the 74HCT04-Q100 family of hex inverters manufactured by Nexperia. The 'DB' designation indicates the SO14 package variant, while 'Q100' signifies automotive qualification. The 'J' suffix typically denotes tape and reel packaging, though verification with official ordering information is recommended. This series provides a reliable solution for signal inversion in harsh environments.

Replacement Considerations

Direct functional equivalents include other AEC-Q100 qualified hex inverters from major manufacturers such as NXP or STMicroelectronics. When substituting, verify pinout compatibility, electrical characteristics including propagation delay and output drive strength, and ensure the replacement part meets the same temperature and voltage requirements.
