74LVC06AD,112 Inverter IC – Equivalent & Substitute Parts

Part Overview

The 74LVC06AD,112 is a 6-channel inverter IC with open-drain outputs manufactured by Nexperia USA Inc. in a 14-SO package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The 74LVC06 series provides logic inversion functionality suitable for applications requiring open-drain output capability across a wide supply voltage range. Substitute parts maintain the same functional architecture—6 inverter channels with single input per channel and open-drain output configuration—while offering active product status and improved availability.

Engineering Selection Recommendations

Primary Recommendation: Texas Instruments 74LVC06 Series

The Texas Instruments SN74LVC06 variants (SN74LVC06AD, SN74LVC06ADR, SN74LVC06ADT, SN74LVC06ANSR, SN74LVC06AQDRQ1, SN74LVC06AQDRG4Q1) are the preferred substitutes for the obsolete 74LVC06AD,112. These parts maintain the 74LVC base series designation, offer active product status, and provide ROHS3 compliance with MSL 1 rating.

For Standard Industrial Applications: SN74LVC06ADR or SN74LVC06ADT are suitable for applications operating within the 1.65V – 3.6V supply range. Both parts are available in Tape & Reel packaging with active status and equivalent functional performance.

For Extended Temperature Range: SN74LVC06ANS extends the operating temperature to –55°C to 125°C, providing broader environmental coverage than the base 74LVC06AD,112 specification.

For Automotive Applications: SN74LVC06AQDRQ1 and SN74LVC06AQDRG4Q1 are AEC-Q100 qualified automotive-grade variants with active status, suitable for automotive and mission-critical applications.

Secondary Recommendation: onsemi 74LCX06 Series

MC74LCX06DG and MC74LCX06DR2G provide functional equivalence with a narrower supply voltage range (2V – 3.6V). These parts are suitable only for applications that do not require operation below 2V. Both variants are active and ROHS3 compliant.

Supply Voltage Consideration:

The original 74LVC06AD,112 supports 1.2V – 5.5V operation. Substitute parts operate within narrower ranges:

Texas Instruments 74LVC06: 1.65V – 3.6V
onsemi 74LCX06: 2V – 3.6V

Applications requiring operation above 3.6V or below 1.65V cannot use these substitutes.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 74LVC06AD,112 with any of the listed substitutes?

A: Direct replacement is possible only if your application operates within the supply voltage range of the substitute part. The original part supports 1.2V – 5.5V, while most substitutes operate within 1.65V – 3.6V or 2V – 3.6V. Verify your circuit's supply voltage before selection.

Q: What is the difference between the Texas Instruments and onsemi variants?

A: Both manufacturers provide 6-channel inverter ICs with open-drain outputs in compatible packages. The primary differences are supply voltage range (TI: 1.65V – 3.6V; onsemi: 2V – 3.6V), quiescent current specifications, and propagation delay characteristics. Texas Instruments variants offer lower quiescent current in some models (1 µA vs. 10 µA).

Q: Are the 14-SOIC and 14-SO packages interchangeable?

A: The 14-SOIC (0.154", 3.90mm width) and 14-SO (0.209", 5.30mm width) packages have different physical dimensions. Verify your PCB footprint before selecting a part. Most substitutes use the narrower 14-SOIC (0.154") package, while SN74LVC06ANS and SN74LVC06ANSR use the wider 14-SO (0.209") package.

Q: Which substitute should I use for automotive applications?

A: SN74LVC06AQDRQ1 and SN74LVC06AQDRG4Q1 are AEC-Q100 qualified and designated for automotive use. These parts maintain active product status and full ROHS3 compliance.

Q: What is the impact of lower output current in substitutes?

A: The original 74LVC06AD,112 provides 32 mA output low current, while substitutes provide 24 mA. If your application requires driving loads with higher current demands, verify that 24 mA is sufficient for your output stage design.

Q: Can I use the onsemi MC74LCX06 series if my application operates at 1.5V?

A: No. The onsemi 74LCX06 series minimum supply voltage is 2V. Applications requiring operation below 2V must use Texas Instruments 74LVC06 variants (minimum 1.65V) or the original Nexperia part if still available.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance of the original 74LVC06AD,112.
