MM74HCU04SJ Equivalent & Substitute Parts

Part Overview

The MM74HCU04SJ is a 6-channel inverter logic IC manufactured by onsemi in 14-SOP surface mount packaging. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The MM74HCU04SJ operates across a 2V to 6V supply voltage range and is suitable for CMOS logic applications requiring signal inversion across multiple channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MM74HCU04SJ is determined by the following critical parameters:

• Logic Function: All substitutes must be 6-channel inverters with single input per channel
• Supply Voltage Range: Minimum 2V ~ 6V compatibility required
• Quiescent Current: Maximum 2 µA specification
• Propagation Delay: Maximum 14ns at 6V with 50pF load
• Operating Temperature: Minimum -40°C ~ 85°C range
• Mounting Type: Surface mount only
• Package Compatibility: 14-SOIC footprint with compatible pin assignments

Substitutes are grouped into two categories:

Direct Substitutes maintain identical electrical specifications and package dimensions, enabling pin-for-pin replacement.

Similar Substitutes maintain core logic functionality and electrical performance within specified ranges but may differ in product status, temperature range, or packaging format. These require design verification for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

SN74HCU04NSR (Texas Instruments) is the primary recommended direct substitute. This part maintains identical electrical specifications and package dimensions (14-SOIC 0.209" width) as the MM74HCU04SJ, enabling direct pin-for-pin replacement. The SN74HCU04NSR is in active production status with ROHS3 compliance and is available in Tape & Reel packaging format.

CD74HCU04M96 (Texas Instruments) and SN74HCU04DR (Texas Instruments) are active production alternatives with extended operating temperature range (-55°C ~ 125°C) and improved propagation delay performance (12ns). These parts use a narrower 14-SOIC package (0.154" width) and require PCB layout verification for footprint compatibility.

SN74HCU04D (Texas Instruments) and SN74HCU04DT (Texas Instruments) are classified as Last Time Buy and should be considered only when long-term supply continuity is not a design requirement.

74HCU04D,652 and 74HCU04D,653 (NXP Semiconductors) are active production alternatives with high inventory availability. Detailed electrical specifications are not provided in the data; verification against application requirements is necessary before selection.

Frequently Asked Questions (FAQ)

Q: Can SN74HCU04NSR replace MM74HCU04SJ directly without PCB modification?

A: Yes. The SN74HCU04NSR maintains identical electrical specifications and package dimensions (14-SOIC 0.209" width), enabling direct pin-for-pin replacement without PCB layout changes.

Q: What is the difference between the 0.209" and 0.154" SOIC package widths?

A: Both are 14-SOIC packages with identical pin pitch and lead spacing. The width difference reflects the body width of the component. The 0.154" variant (used by CD74HCU04M96, SN74HCU04D, SN74HCU04DR, SN74HCU04DT) is narrower and requires verification that PCB footprints accommodate this dimension. Pin-to-pin compatibility remains identical.

Q: Why do some substitutes have different output current specifications?

A: The MM74HCU04SJ specifies asymmetrical output current (5.2mA high, 7.8mA low), while most Texas Instruments substitutes specify symmetrical output current (5.2mA both directions). Both meet the functional requirements for inverter operation; the difference reflects manufacturing process variations between onsemi and Texas Instruments.

Q: Are CD74HCU04M and CD74HCU04M96 interchangeable?

A: Both parts are functionally equivalent 6-channel inverters with identical electrical specifications. CD74HCU04M is packaged in Tube format and classified as Last Time Buy. CD74HCU04M96 is packaged in Tape & Reel format and is in active production. Selection depends on packaging requirements and supply continuity needs.

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

A: Last Time Buy indicates the manufacturer has announced end-of-life for the part. Existing inventory may be available, but no new production is planned. For new designs or long-term production requirements, select parts with Active status.

Q: Can I use NXP 74HCU04D,652 or 74HCU04D,653 as substitutes?

A: These parts are functionally equivalent 6-channel inverters in active production with high inventory availability. However, detailed electrical specifications are not provided in the available data. Verification against your specific application requirements (voltage levels, timing, temperature range) is necessary before design implementation.
