Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74AC04SJ is determined by the following criteria:

Direct Substitutes maintain identical electrical specifications (voltage supply 2V ~ 6V, quiescent current 2 µA max, output current 24mA, propagation delay 7ns @ 5V 50pF, operating temperature -40°C ~ 85°C) and compatible package footprints. These parts are interchangeable at the functional and electrical level.

Similar Substitutes maintain the core inverter function and 6-channel configuration but may vary in one or more of the following parameters: voltage supply range, quiescent current, propagation delay, operating temperature range, or package dimensions. These parts require design verification to confirm compatibility with the specific application requirements.

The key parameters determining substitution eligibility are:

• Logic function (Inverter, 6 channels, 1 input per channel)
• Voltage supply compatibility
• Output drive capability (24mA minimum)
• Propagation delay performance
• Operating temperature range
• Physical package compatibility with PCB layout

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

SN74AC04NSR and SN74AC04DR are the primary direct substitutes for the 74AC04SJ. Both parts maintain identical electrical specifications and are currently in active product status. SN74AC04NSR is supplied in Tape & Reel packaging with 4790 pcs in stock, while SN74AC04DR is supplied in Cut Tape & Digi-Reel packaging with 10100 pcs in stock. Both are ROHS3 compliant and carry REACH Unaffected status.

SN74AC04NS is functionally equivalent but is discontinued at DiGi Electronics, limiting long-term procurement viability.

Similar Substitutes (Conditional Compatibility):

CD74AC04M96 and SN74AC04MDREP offer extended operating temperature ranges (-55°C ~ 125°C) compared to the 74AC04SJ (-40°C ~ 85°C), making them suitable for applications requiring wider temperature performance. CD74AC04M96 features improved propagation delay (6.5ns vs 7ns) and operates at lower voltage supply minimums (1.5V vs 2V). SN74AC04MDREP maintains identical electrical performance to the 74AC04SJ with extended temperature capability. Both are active products with ROHS3 compliance.

Package footprint differences exist between the 14-SOP (0.209", 5.30mm width) of the 74AC04SJ and the 14-SOIC variants (0.209" or 0.154" width). PCB layout compatibility must be verified before selection.

Frequently Asked Questions (FAQ)

Q: Can SN74AC04NSR directly replace the 74AC04SJ without design changes?

A: SN74AC04NSR is electrically and functionally equivalent to the 74AC04SJ. Both operate at 2V ~ 6V supply voltage, deliver 24mA output current, and exhibit 7ns propagation delay at 5V with 50pF load. The primary consideration is package footprint compatibility. The 74AC04SJ uses a 14-SOP package (0.209", 5.30mm width) while SN74AC04NSR uses a 14-SOIC package (0.209", 5.30mm width). Verify PCB pad layout compatibility before implementation.

Q: What is the difference between SN74AC04DR and SN74AC04NSR?

A: Both parts are electrically identical with matching voltage supply (2V ~ 6V), quiescent current (2 µA), output current (24mA), and propagation delay (7ns @ 5V, 50pF). The primary differences are packaging format (SN74AC04DR supplied in Cut Tape & Digi-Reel; SN74AC04NSR supplied in Tape & Reel) and product status (both active). Selection depends on procurement and assembly requirements.

Q: Why does CD74AC04M96 have different electrical specifications?

A: CD74AC04M96 is designed for extended operating conditions. It operates across a wider voltage supply range (1.5V ~ 5.5V vs 2V ~ 6V), supports extended temperature operation (-55°C ~ 125°C vs -40°C ~ 85°C), and delivers faster propagation delay (6.5ns vs 7ns). These differences reflect a different product variant within the 74AC04 family optimized for broader environmental performance. Application requirements determine whether these differences are beneficial or require design verification.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance status. The original 74AC04SJ does not specify RoHS status in the provided data. All parts are REACH Unaffected and carry EAR99 ECCN classification.

Q: What packaging options are available for the 74AC04 inverter?

A: The 74AC04 inverter function is available in multiple package formats: 14-SOP (0.209", 5.30mm width), 14-SOIC (0.209", 5.30mm width), and 14-SOIC (0.154", 3.90mm width). Packaging is supplied in Tube, Tape & Reel, or Cut Tape & Digi-Reel formats depending on the specific part number and manufacturer. Verify PCB footprint compatibility and assembly process requirements when selecting between package variants.
