74LVC04AD,112 Inverter IC – Equivalent & Substitute Parts

Part Overview

The 74LVC04AD,112 is a 6-channel inverter logic IC manufactured by Nexperia USA Inc., housed in a 14-SOIC package. This part operates across a supply voltage range of 1.2V to 3.6V and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active product lines are necessary for new designs and ongoing production requirements. Substitute parts maintain functional equivalence through matching logic type, circuit count, input configuration, and package compatibility while meeting current RoHS3 and REACH compliance standards.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following parameters:

Logic Function: All substitutes must be 6-channel inverter ICs with single-input configuration
Package Compatibility: Primary substitutes use 14-SOIC (0.154", 3.90mm) packaging; 14-SO (0.209", 5.30mm) variants are functionally equivalent but require PCB layout verification
Output Current: All substitutes deliver 24mA output current (high and low), matching the original specification
Voltage Supply Range: Substitutes must support operation within or encompass the 1.2V–3.6V range
Propagation Delay: Maximum delay at 3.3V, 50pF load must not exceed 5.2ns to maintain timing compatibility
Operating Temperature: Substitutes must support the -40°C to 125°C range or broader
Compliance: All substitutes are RoHS3 compliant and REACH unaffected

Substitute parts are grouped into two categories: 74LVC series (Texas Instruments) and 74LCX series (onsemi), both meeting the functional and electrical requirements of the original part.

Engineering Selection Recommendations

Primary Substitutes (Recommended)

The SN74LVC04 series from Texas Instruments represents the primary substitute family. These parts are in active production status and provide superior electrical characteristics compared to the original 74LVC04AD,112. The SN74LVC04AD, SN74LVC04ADR, SN74LVC04ADRG3, and SN74LVC04ADT variants are functionally identical, differing only in packaging format (tube, cut tape, or tape & reel). Selection among these variants depends on procurement and assembly requirements. All SN74LVC04 variants feature reduced quiescent current (1 µA versus 40 µA) and faster propagation delay (4.3ns versus 4.5ns), providing improved power efficiency and timing performance.

Secondary Substitutes (Conditional)

The MC74LCX04 series from onsemi (MC74LCX04DG and MC74LCX04DR2G) are active production alternatives. These parts operate within a narrower voltage supply range (2V–3.6V) and exhibit slightly higher propagation delay (5.2ns). The MC74LCX04DG supports an extended operating temperature range (-55°C to 125°C), making it suitable for applications requiring broader temperature coverage. The MC74LCX04DR2G is available in tape & reel packaging for high-volume production.

Package Considerations

The SN74LVC04ANS and SN74LVC04ANSR variants use a wider 14-SOIC package (0.209", 5.30mm width) compared to the standard 14-SOIC (0.154", 3.90mm width). These parts are functionally equivalent but require verification of PCB footprint compatibility before selection.

Compliance Status

All recommended substitutes are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 74LVC04AD,112 with SN74LVC04AD in my design?

A: Yes. Both parts are 6-channel inverter ICs in 14-SOIC (0.154") packaging with identical logic function, output current (24mA), and operating temperature range (-40°C to 125°C). The SN74LVC04AD offers improved specifications: lower quiescent current (1 µA vs. 40 µA) and faster propagation delay (4.3ns vs. 4.5ns). No circuit modifications are required.

Q: What is the difference between SN74LVC04AD, SN74LVC04ADR, and SN74LVC04ADRG3?

A: These three parts are electrically identical. The differences are packaging formats: SN74LVC04AD is supplied in tube packaging, SN74LVC04ADR in cut tape & Digi-Reel format, and SN74LVC04ADRG3 in tape & reel format. Selection depends on your procurement and assembly process requirements.

Q: Why does SN74LVC04ANS have a different package size?

A: The SN74LVC04ANS uses a 14-SOIC package with 0.209" width (5.30mm) instead of the standard 0.154" width (3.90mm). This is a wider package variant. Verify your PCB footprint before selecting this part. The electrical function remains identical.

Q: Can I use MC74LCX04DG as a substitute?

A: Yes, with considerations. The MC74LCX04DG is functionally equivalent but operates within a narrower voltage range (2V–3.6V vs. 1.2V–3.6V) and has slightly higher propagation delay (5.2ns vs. 4.5ns). If your circuit operates above 2V and timing margins accommodate the additional delay, this part is suitable. The extended temperature range (-55°C to 125°C) is beneficial for extreme temperature applications.

Q: Is 74LCX04M still available for new designs?

A: No. The 74LCX04M is obsolete. Use active alternatives from the SN74LVC04 or MC74LCX04 series instead.

Q: What is the minimum voltage at which these inverter ICs operate?

A: The SN74LVC04 series operates from 1.65V minimum, while the MC74LCX04 series requires 2V minimum. The original 74LVC04AD,112 specified 1.2V minimum. If your design requires operation below 1.65V, verify compatibility with your specific application requirements.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All recommended substitute parts are RoHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement and assembly.
