74HCT04D/AUJ

Overview

The NXP USA Inc. 74HCT04D/AUJ is a hex inverter belonging to the 74HCT logic family, manufactured by Nexperia. It contains six independent inverters within a single package. The device operates with a supply voltage range of 2.0 V to 6.0 V and complies with JEDEC standards JESD8C and JESD7A. It features TTL input levels and CMOS low power dissipation. The component utilizes an SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm. It supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Contains six independent inverting channels for signal inversion applications.
• Inputs include clamp diodes allowing interface to voltages exceeding VCC using current limiting resistors.
• Provides high noise immunity and low power consumption characteristics typical of CMOS technology.
• Offers robust electrostatic discharge protection meeting specified JEDEC class requirements.

Applications

• Signal inversion in digital logic circuits
• Clock signal generation and conditioning
• Level shifting between different logic families

Procurement Notes

Verify that the ordering suffix AUJ corresponds to the specific SO14 package variant SOT108-1 as defined in the official datasheet. Confirm the manufacturer origin is Nexperia, which succeeded NXP's standard logic business. Ensure the procurement documentation references the correct product data sheet revision to guarantee compliance with the latest ESD specifications and pinning details.

Selection Notes

Select this component when a hex inverter with TTL-compatible input thresholds is required within a CMOS system. The HCT series ensures compatibility with standard TTL logic outputs while maintaining lower power consumption. Consider the wide supply voltage capability and extended temperature range if the application environment demands operation beyond standard commercial limits.

Part Context

This part belongs to the widely used 74HCT04 hex inverter family, standardized under JEDEC specifications. The D/AUJ designation identifies the specific surface-mount packaging configuration. This family serves as a fundamental building block for digital electronics, providing reliable inversion functions across various industrial and consumer applications requiring standard logic interfacing.

Replacement Considerations

Direct functional equivalents include other manufacturers' 74HCT04 devices in SOIC-14 packages. Verify pinout compatibility and electrical parameters such as propagation delay and output drive strength before substitution. Cross-reference with Nexperia's official replacement guide for any updated package options or automotive qualified variants.
