74ACTQ04SJX Equivalent & Substitute Parts

Part Overview

The 74ACTQ04SJX is a 6-channel inverter logic IC manufactured by onsemi in a 14-SOP surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The 74ACTQ04SJX operates within the 74ACT logic family standard, which defines compatible alternatives based on electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ACTQ04SJX is determined by the following criteria:

Mandatory Matching Parameters:

• Logic Type: Inverter
• Number of Circuits: 6
• Number of Inputs: 1
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Output High, Low: 24mA, 24mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Mounting Type: Surface Mount
• Base Product Number: 74ACT04 series

Allowable Variations:

• Current - Quiescent (Max): May vary within manufacturer specifications
• Max Propagation Delay: May vary within acceptable timing margins
• Operating Temperature: May extend beyond original range
• Package / Case: Mechanical dimensions may differ while maintaining 14-pin SOIC footprint compatibility
• Product Status: Active or discontinued parts are acceptable alternatives to obsolete parts
• Compliance certifications: RoHS and REACH status may differ

All substitute parts listed maintain functional equivalence within the 74ACT logic family standard and are pin-compatible with the 74ACTQ04SJX.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74ACT04DR (Texas Instruments)

The SN74ACT04DR is the preferred substitute for the 74ACTQ04SJX. This part maintains identical electrical specifications, operates within the same temperature range, and carries active product status with ROHS3 compliance. The 14-SOIC package dimensions (0.154", 3.90mm Width) differ from the original, requiring PCB layout verification for mechanical fit.

Secondary Recommendation: SN74ACT04NSR (Texas Instruments)

The SN74ACT04NSR provides an alternative with matching electrical performance and active product status. This part maintains the original package width (0.209", 5.30mm), offering direct mechanical compatibility with the 74ACTQ04SJX footprint. ROHS3 compliance and REACH compliance are confirmed.

Alternative: CD74ACT04M96 (Harris Corporation)

The CD74ACT04M96 is functionally equivalent but carries obsolete product status and RoHS non-compliance. This part exhibits higher quiescent current (4 µA vs. 2 µA) and extended propagation delay (9.3ns vs. 7.5ns). Selection of this part is not recommended for new designs.

Alternative: SN74ACT04D (Texas Instruments)

The SN74ACT04D is discontinued at DiGi Electronics but maintains electrical equivalence and ROHS3 compliance. Availability may be limited through alternative distribution channels.

Frequently Asked Questions (FAQ)

Q: Can I use SN74ACT04NSR as a direct replacement for 74ACTQ04SJX?

A: Yes. The SN74ACT04NSR maintains identical electrical specifications, operating temperature range, and package width (0.209", 5.30mm), providing direct pin and mechanical compatibility.

Q: What is the difference between the 14-SOIC packages listed?

A: The packages differ in width: 0.209" (5.30mm) versus 0.154" (3.90mm). Both are 14-pin SOIC packages with identical pin pitch and electrical connectivity. PCB footprint verification is required when substituting between these package variants.

Q: Is the CD74ACT04M96 suitable for new designs?

A: No. This part is obsolete and RoHS non-compliant. It exhibits higher quiescent current and longer propagation delay than the original specification. Active alternatives such as SN74ACT04DR or SN74ACT04NSR are recommended.

Q: What does "ROHS3 Compliant" mean for substitution purposes?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements. Parts with this certification are suitable for applications requiring environmental compliance. The original 74ACTQ04SJX carries REACH Unaffected status, which differs from ROHS3 compliance but does not prevent substitution.

Q: Are all substitute parts pin-compatible with the 74ACTQ04SJX?

A: Yes. All listed substitutes maintain the 6-channel inverter configuration with 1 input per channel in a 14-pin SOIC package, ensuring pin-for-pin compatibility.

Q: Which substitute has the fastest propagation delay?

A: The 74ACTQ04SJX and all Texas Instruments substitutes (SN74ACT04D, SN74ACT04DR, SN74ACT04NSR) specify 8.5ns propagation delay at 5V with 50pF load, matching or exceeding the original 7.5ns specification. The CD74ACT04M96 specifies 9.3ns.
