SN74LVC06APWRG4 Equivalent & Substitute Parts

Part Overview

The SN74LVC06APWRG4 is a 6-channel inverter IC with open-drain outputs in a 14-TSSOP surface mount package, manufactured by Texas Instruments. This part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. The device operates across a 1.65V to 3.6V supply voltage range with low quiescent current and fast propagation delay characteristics suitable for logic-level signal inversion in embedded systems and digital circuits.

Substitute Part Grouping Explanation

Substitution for the SN74LVC06APWRG4 is determined by strict equivalence across the following critical parameters:

Logic type (Inverter) and circuit configuration (6-channel, 1-input)
Open-drain output feature
Package type (14-TSSOP surface mount)
Supply voltage range compatibility
Output current capability (24mA minimum)
Input logic level thresholds
Propagation delay performance
Operating temperature range
RoHS and compliance certifications

Substitute parts are grouped into two categories: direct manufacturer equivalents from Texas Instruments with identical electrical specifications, and cross-manufacturer alternatives with compatible but slightly different electrical parameters that remain functionally equivalent within the 14-TSSOP package constraint.

Engineering Selection Recommendations

Primary Recommendation: SN74LVC06APWR (Texas Instruments)

The SN74LVC06APWR is the direct active equivalent to the discontinued SN74LVC06APWRG4. It maintains identical electrical specifications, supply voltage range, quiescent current, output current capability, and propagation delay. Both parts are ROHS3 compliant with MSL Level 1 rating. The only difference is packaging format (Tape & Reel vs. standard packaging), which does not affect functional performance. This part has 8,300 units in stock.

Secondary Recommendation: SN74LVC06APWT (Texas Instruments)

The SN74LVC06APWT provides identical electrical performance to the main part with active product status and ROHS3 compliance. Inventory availability is 2,247 units. Selection between SN74LVC06APWR and SN74LVC06APWT depends on packaging and supply chain requirements.

Cross-Manufacturer Alternatives: 74LCX06MTCX (Fairchild) and MC74LCX06DTR2G (onsemi)

Both the 74LCX06MTCX and MC74LCX06DTR2G are functionally compatible alternatives with the following trade-offs: minimum supply voltage increases to 2V (vs. 1.65V), quiescent current increases to 10 µA (vs. 1 µA), and maximum operating temperature is limited to 85°C (vs. 125°C). Propagation delay increases slightly to 3.7ns. These parts are suitable for applications not requiring the extended low-voltage operation or full temperature range of the original part. Both are ROHS3 compliant.

Extended Range Alternative: 74LVC06APW-Q100J (NXP USA Inc.)

The 74LVC06APW-Q100J offers extended supply voltage range (1.2V to 5.5V) and higher output current (32mA), with faster propagation delay at 5V operation (2.5ns). This part is active with 6,201 units in stock and maintains the -40°C to 125°C operating range. Selection of this part is appropriate for applications requiring wider voltage compatibility or higher output drive capability.

Frequently Asked Questions (FAQ)

Q: Can I directly replace SN74LVC06APWRG4 with SN74LVC06APWR?

A: Yes. Both parts are Texas Instruments 74LVC06 inverters with identical electrical specifications, supply voltage range (1.65V ~ 3.6V), quiescent current (1 µA), output current (24mA), and propagation delay (4.6ns @ 3.3V). The difference is packaging format only. Both are ROHS3 compliant with MSL Level 1.

Q: What are the limitations of using 74LCX06MTCX or MC74LCX06DTR2G as substitutes?

A: These Fairchild and onsemi alternatives have three key limitations: minimum supply voltage is 2V instead of 1.65V, quiescent current is 10 µA instead of 1 µA, and maximum operating temperature is 85°C instead of 125°C. Propagation delay is slightly longer at 3.7ns. Use these parts only if your application does not require low-voltage operation below 2V or extended temperature operation above 85°C.

Q: Is the 74LVC06APW-Q100J suitable for my application?

A: The 74LVC06APW-Q100J is suitable if your application requires extended supply voltage range (1.2V ~ 5.5V) or higher output current (32mA vs. 24mA). It maintains the full -40°C to 125°C operating range and offers faster propagation delay at higher voltages. Verify that your circuit design can accommodate the wider voltage specification.

Q: Are all substitute parts available in 14-TSSOP package?

A: Yes. All listed substitute parts are available in 14-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width), ensuring direct PCB compatibility without layout modifications.

Q: What is the difference between SN74LVC06APWR and SN74LVC06APWT?

A: Both parts are electrically identical Texas Instruments 74LVC06 inverters with active product status. The difference is in packaging format: SN74LVC06APWR is supplied in Tape & Reel format, while SN74LVC06APWT is also in Tape & Reel format. Selection depends on your procurement and assembly requirements.

Q: Do all substitute parts meet RoHS compliance?

A: The Texas Instruments parts (SN74LVC06APWR, SN74LVC06APWT), Fairchild 74LCX06MTCX, and onsemi MC74LCX06DTR2G are all ROHS3 compliant. The NXP 74LVC06APW,118 and 74LVC06APW-Q100J compliance status is confirmed as REACH Unaffected. Verify specific compliance documentation for your regulatory requirements.
