SN74LVC08AQPWREP Equivalent & Substitute Parts

Part Overview

The SN74LVC08AQPWREP is a 4-channel 2-input AND gate logic IC manufactured by Texas Instruments, housed in a 14-TSSOP surface mount package. This device operates across a 2V to 3.6V supply voltage range and is designed for low-power digital logic applications. The part is currently active in production with 950 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when specific packaging or qualification requirements must be met, or when alternative manufacturers' equivalents offer improved inventory availability or lead times while maintaining functional compatibility.

Engineering Selection Recommendations

Texas Instruments Parametric Equivalents (SN74LVC08AQPWRG4Q1, SN74LVC08AQPWRQ1): These parts are direct functional equivalents with identical electrical specifications and operating temperature range. Both carry AEC-Q100 automotive qualification. Selection between these and the primary part depends on packaging format requirements: Tape & Reel (TR) for automated assembly processes versus Tube for manual handling. Inventory availability is significantly higher for SN74LVC08AQPWRQ1 (12,100 units) compared to the primary part (950 units).

onsemi 74LCX Series (74LCX08MTCX, MC74LCX08DTG, MC74LCX08DTR2G): These parts maintain functional compatibility with identical quiescent current and output drive specifications. The 74LCX series operates within the same 2V to 3.6V supply range. Maximum propagation delay is 5.5ns at 3.3V and 50pF load, which is 1.4ns slower than the primary part. Operating temperature range is limited to -40°C to 85°C. These parts are suitable for applications where the extended propagation delay and reduced upper temperature limit are acceptable. Inventory availability is high (45,555 units for 74LCX08MTCX).

Nexperia 74LVC08 Series (74LVC08ADB,112, 74LVC08APW,118): The 74LVC08APW,118 is an active product with identical propagation delay and operating temperature range to the primary part. It supports an extended lower supply voltage limit of 1.2V and higher quiescent current of 40 µA. The 14-TSSOP package matches the primary part. The 74LVC08ADB,112 is obsolete and should not be selected for new designs.

Recommendation Priority:

SN74LVC08AQPWRQ1 for highest inventory availability with identical specifications
SN74LVC08AQPWRG4Q1 for automotive-qualified Tape & Reel packaging
74LVC08APW,118 for active production status with extended voltage range
74LCX08MTCX or MC74LCX08DTR2G only when propagation delay tolerance and reduced temperature range are acceptable

Frequently Asked Questions (FAQ)

Q: Can I substitute the SN74LVC08AQPWREP with the 74LCX08MTCX? A: Yes, with performance considerations. The 74LCX08MTCX maintains the same logic function, circuit count, input count, and output drive specifications. However, propagation delay increases from 4.1ns to 5.5ns, and the maximum operating temperature is reduced from 125°C to 85°C. Verify that your application tolerates these performance differences before substitution.

Q: What is the difference between SN74LVC08AQPWREP and SN74LVC08AQPWRQ1? A: Both parts are electrically identical with the same voltage supply range, quiescent current, propagation delay, and operating temperature. The primary difference is packaging format: SN74LVC08AQPWREP is supplied in Tube packaging, while SN74LVC08AQPWRQ1 is supplied in Tape & Reel (TR) format. SN74LVC08AQPWRQ1 also carries AEC-Q100 automotive qualification and has significantly higher inventory availability (12,100 units versus 950 units).

Q: Why does the 74LVC08APW,118 have different quiescent current specifications? A: The 74LVC08APW,118 from Nexperia operates across a wider supply voltage range (1.2V to 3.6V) compared to the primary part (2V to 3.6V). The extended lower voltage capability results in higher quiescent current of 40 µA versus 10 µA. Propagation delay and operating temperature range remain identical to the primary part.

Q: Is the 14-TSSOP package compatible with 14-SSOP? A: No. The 14-TSSOP package has a width of 0.173" (4.40mm), while the 14-SSOP package has a width of 0.209" (5.30mm). These are different physical packages and are not interchangeable on the same PCB footprint. The 74LVC08ADB,112 uses 14-SSOP and cannot be directly substituted for the primary part without PCB redesign.

Q: Can I use the 74LCX08MTCX in a design requiring -40°C to 125°C operation? A: No. The 74LCX08MTCX is rated only to 85°C maximum operating temperature. For applications requiring the full -40°C to 125°C range, use the SN74LVC08AQPWREP, SN74LVC08AQPWRG4Q1, SN74LVC08AQPWRQ1, or 74LVC08APW,118.

Q: What does AEC-Q100 qualification mean? A: AEC-Q100 is an automotive industry qualification standard. Parts carrying this certification have been tested and validated for automotive applications. SN74LVC08AQPWRG4Q1 and SN74LVC08AQPWRQ1 both carry AEC-Q100 qualification, making them suitable for automotive designs requiring this certification.
