Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HCU04D,652 is determined by the following criteria:

Functional Equivalence: All substitute parts maintain the same logic type (inverter), circuit count (6 channels), input configuration (1 input per channel), and package form factor (14-SOIC).

Electrical Compatibility: Substitute parts must operate within the 2V to 6V supply voltage range and maintain compatible output current specifications (5.2mA nominal for output high and low states).

Timing Specifications: Maximum propagation delay at 6V with 50pF load must not exceed 12ns to 14ns, ensuring functional compatibility in timing-critical applications.

Temperature Range: Parts are grouped by operating temperature capability. The main part operates -40°C to 125°C. Substitutes with -55°C to 125°C or -40°C to 85°C ranges are acceptable depending on application requirements.

Packaging and Compliance: All substitutes use 14-SOIC surface mount packaging with ROHS3 compliance and MSL 1 rating, ensuring manufacturing and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Highest Compatibility)

The 74HCU04D,653 from NXP Semiconductors is the closest equivalent, maintaining identical electrical specifications and operating temperature range. This part is currently active and available in bulk packaging.

Extended Temperature Range Alternatives

CD74HCU04M96 (Texas Instruments, Active) and MC74HCU04ADR2G (onsemi, Active) both extend the operating temperature range to -55°C to 125°C, providing enhanced low-temperature performance. These parts are suitable for applications requiring wider temperature operation.

Standard Temperature Range Alternatives

SN74HCU04DR (Texas Instruments, Active) and MM74HCU04M (onsemi, Active) maintain the -40°C to 85°C operating range with active product status. SN74HCU04DR is available in Tape & Reel packaging for automated assembly.

Packaging Considerations

For tube packaging, select CD74HCU04M, MC74HCU04ADG, MM74HCU04M, or SN74HCU04D. For Tape & Reel packaging suitable for pick-and-place assembly, select CD74HCU04M96, MC74HCU04ADR2G, or SN74HCU04DR.

Obsolete Part Avoidance

NLV74HCU04ADR2G is obsolete and should not be selected for new designs despite its extended temperature range and automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can I use any 74HCU04 variant as a direct replacement for the 74HCU04D,652?

A: Not all variants are equivalent. The main part operates at -40°C to 125°C with 12ns propagation delay. Substitutes with 14ns propagation delay (SN74HCU04D, SN74HCU04DR, MM74HCU04M) or narrower temperature ranges (-40°C to 85°C) may not be suitable for all applications. Verify your application's timing and temperature requirements before selection.

Q: What is the difference between tube and Tape & Reel packaging?

A: Tube packaging is suitable for manual handling and lower-volume assembly. Tape & Reel packaging is designed for automated pick-and-place equipment and high-volume production. Both formats contain identical die and electrical specifications.

Q: Why do some substitutes have lower quiescent current (1 µA vs 2 µA)?

A: Lower quiescent current indicates improved power efficiency in standby conditions. MC74HCU04ADG and MC74HCU04ADR2G from onsemi specify 1 µA maximum quiescent current, making them suitable for battery-powered or low-power applications. This is a beneficial characteristic and does not affect functional compatibility.

Q: Are all listed substitutes ROHS3 compliant?

A: All substitutes with specified RoHS status are ROHS3 compliant. Parts without explicitly stated RoHS status should be verified with the manufacturer before use in applications requiring RoHS compliance.

Q: What does "Last Time Buy" product status mean?

A: Last Time Buy indicates the manufacturer will no longer produce the part after a specified date. CD74HCU04M and SN74HCU04D are in this status. For long-term production, select parts with Active status: CD74HCU04M96, MC74HCU04ADG, MC74HCU04ADR2G, MM74HCU04M, MM74HCU04MX, or SN74HCU04DR.

Q: Can I use NLV74HCU04ADR2G as a substitute despite its obsolete status?

A: NLV74HCU04ADR2G is obsolete and should not be selected for new designs. Although it offers extended temperature range and automotive qualification, its discontinuation status makes it unsuitable for production applications requiring long-term supply assurance.
