Engineering Selection Recommendations

Primary Recommendation: SN74LVC86APWR

The SN74LVC86APWR is the direct functional equivalent manufactured by Texas Instruments with active product status. This part maintains identical electrical specifications to the discontinued SN74LVC86APWRG4, including supply voltage range (1.65V ~ 3.6V), quiescent current (1 µA), propagation delay (4.4ns @ 3.3V, 50pF), and operating temperature range (-40°C ~ 125°C). The part is ROHS3 compliant with MSL rating of 1 (Unlimited). Packaging is 14-TSSOP surface mount with 2400 units currently in stock.

Secondary Recommendation: 74LVC86APW,118

The 74LVC86APW,118 from Nexperia USA Inc. provides functional equivalence with active product status. This part extends the lower supply voltage limit to 1.2V and maintains the same operating temperature range (-40°C ~ 125°C). Quiescent current is elevated to 40 µA and propagation delay increases to 5ns @ 3.3V, 50pF. ROHS3 compliance and MSL rating of 1 (Unlimited) are maintained. This option is suitable for applications requiring extended low-voltage operation. 3700 units are in stock.

Alternative Options: 74LCX86MTCX and MC74LCX86DTR2G

Both the Fairchild Semiconductor 74LCX86MTCX and onsemi MC74LCX86DTR2G are functionally equivalent XOR logic gates in 14-TSSOP packages. These parts operate within a narrower supply voltage range (2V ~ 3.6V) and reduced operating temperature range (-40°C ~ 85°C). Quiescent current is 10 µA and propagation delay is 6.5ns @ 3.3V, 50pF. These options are suitable for applications where the lower voltage and temperature limits are not critical. 16823 units of 74LCX86MTCX and 2200 units of MC74LCX86DTR2G are available.

Parametric Equivalent: SN74LVC86APWT

The SN74LVC86APWT from Texas Instruments is a parametric equivalent with identical electrical specifications to the main part but carries discontinued product status. This part should be considered only when primary and secondary recommendations are unavailable. 994 units remain in stock.

Frequently Asked Questions (FAQ)

Q: Can I use SN74LVC86APWR as a direct replacement for SN74LVC86APWRG4?

A: Yes. The SN74LVC86APWR is electrically and mechanically identical to the SN74LVC86APWRG4. Both are 4-channel XOR logic gates in 14-TSSOP packages with identical supply voltage ranges (1.65V ~ 3.6V), quiescent current (1 µA), output drive capability (24mA), and operating temperature range (-40°C ~ 125°C). The primary difference is product status: SN74LVC86APWR is active while SN74LVC86APWRG4 is discontinued.

Q: What are the key differences between the Texas Instruments 74LVC series and the 74LCX series substitutes?

A: The 74LVC series (SN74LVC86APWR, 74LVC86APW,118) supports a lower supply voltage minimum of 1.65V or 1.2V respectively, compared to 2V for the 74LCX series (74LCX86MTCX, MC74LCX86DTR2G). The 74LVC series maintains an operating temperature range of -40°C ~ 125°C, while 74LCX series is limited to -40°C ~ 85°C. Quiescent current is lower in 74LVC parts (1 µA to 40 µA) versus 74LCX parts (10 µA). Propagation delay is faster in 74LVC parts (4.4ns to 5ns) compared to 74LCX parts (6.5ns).

Q: Are all substitute parts ROHS3 compliant?

A: ROHS3 compliance is confirmed for SN74LVC86APWR, SN74LVC86APWT, 74LVC86APW,118, and MC74LCX86DTR2G. ROHS status is not specified for 74LCX86MTCX from Fairchild Semiconductor. Verify compliance documentation with the supplier if ROHS3 certification is a requirement for your application.

Q: Can I use 74LVC86APW,118 in applications requiring operation below 1.65V?

A: Yes. The 74LVC86APW,118 supports supply voltage operation down to 1.2V, extending the lower voltage limit by 0.45V compared to the main part. However, quiescent current increases to 40 µA and propagation delay increases to 5ns @ 3.3V, 50pF. Confirm that these parametric changes are acceptable for your circuit design.

Q: What is the impact of using 74LCX series parts in temperature-critical applications?

A: The 74LCX series (74LCX86MTCX, MC74LCX86DTR2G) operates only to 85°C maximum, compared to 125°C for 74LVC series parts. If your application requires operation above 85°C, 74LCX parts are not suitable. Additionally, 74LCX parts require minimum supply voltage of 2V, eliminating compatibility with circuits operating below this threshold.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are housed in 14-TSSOP surface mount packages with identical physical dimensions (0.173" × 4.40mm width). PCB footprints and reflow soldering profiles are compatible across all listed alternatives.

Q: Which substitute offers the best low-power performance?

A: The SN74LVC86APWR and SN74LVC86APWT both provide the lowest quiescent current at 1 µA maximum, matching the main part specification. The 74LCX86MTCX and MC74LCX86DTR2G consume 10 µA, while 74LVC86APW,118 consumes 40 µA. For power-sensitive applications, Texas Instruments 74LVC parts are preferred.
