Substitute Part Grouping Explanation
Substitution for the 74LVC86APW,112 is determined by the following critical parameters:
- Logic Function: All substitutes must implement 4-channel, 2-input XOR logic
- Package Type: Primary substitutes maintain 14-TSSOP packaging for direct board-level compatibility
- Supply Voltage Range: Substitutes must support the operating voltage envelope of the application
- Output Drive Capability: All candidates provide 24mA output current (high and low)
- Propagation Delay: Timing performance must meet or exceed the original specification
- Operating Temperature: Extended temperature range (-40°C to 125°C) is maintained across primary substitutes
- Surface Mount Compatibility: All substitutes use surface mount technology
Substitutes are grouped into two categories:
Category A - Direct Replacements (14-TSSOP, Extended Temperature): Texas Instruments SN74LVC86 series parts (SN74LVC86APW, SN74LVC86ADBR, SN74LVC86APWR, SN74LVC86AQPWREP, SN74LVC86AQPWRG4Q1, SN74LVC86AQPWRQ1) maintain the 14-TSSOP package and -40°C to 125°C operating range with improved quiescent current performance (1 µA vs. 40 µA).
Category B - Functional Equivalents (14-TSSOP, Reduced Temperature): Fairchild Semiconductor 74LCX86MTCX and onsemi MC74LCX86DTR2G provide XOR logic in 14-TSSOP packaging with reduced operating temperature range (-40°C to 85°C) and lower quiescent current (10 µA).

Engineering Selection Recommendations
Primary Substitutes (Recommended)
SN74LVC86APW, SN74LVC86APWR, and SN74LVC86ADBR are the preferred substitutes. All are manufactured by Texas Instruments, maintain active product status, and preserve the -40°C to 125°C operating temperature range of the original part. These parts demonstrate improved quiescent current performance (1 µA vs. 40 µA) and faster propagation delay (4.4ns vs. 5ns). SN74LVC86APW and SN74LVC86APWR maintain 14-TSSOP packaging for direct board compatibility. SN74LVC86ADBR uses 14-SSOP packaging, which requires PCB layout adjustment but is functionally equivalent.
Automotive-Grade Alternatives
SN74LVC86AQPWRG4Q1 and SN74LVC86AQPWRQ1 are AEC-Q100 qualified automotive-grade variants from Texas Instruments. These parts maintain the -40°C to 125°C temperature range and 14-TSSOP packaging. Quiescent current is 10 µA and propagation delay is 4.6ns. These are suitable for applications requiring automotive qualification.
Secondary Substitutes (Functional Equivalents)
74LCX86MTCX (Fairchild Semiconductor) and MC74LCX86DTR2G (onsemi) provide XOR logic functionality in 14-TSSOP packaging with active product status. Both operate at 2V to 3.6V supply voltage with 10 µA quiescent current. The operating temperature range is reduced to -40°C to 85°C, and propagation delay is 6.5ns. These substitutes are suitable only for applications where the reduced temperature range and slower timing are acceptable.
Discontinued Parts
SN74LVC86APWG4 and SN74LVC86APWT are discontinued at DiGi Electronics and should not be selected for new designs despite technical compatibility.
Frequently Asked Questions (FAQ)
Q: Can SN74LVC86ADBR replace 74LVC86APW,112 directly on the PCB?
A: SN74LVC86ADBR is functionally equivalent but uses 14-SSOP packaging instead of 14-TSSOP. The pin count and function are identical, but the package footprint differs (5.30mm width vs. 4.40mm width). PCB layout modification is required.
Q: What is the difference between 74LCX86MTCX and SN74LVC86APW?
A: Both are 4-channel XOR ICs in 14-TSSOP packaging. The primary differences are: (1) operating temperature range is -40°C to 85°C for 74LCX86MTCX vs. -40°C to 125°C for SN74LVC86APW; (2) propagation delay is 6.5ns vs. 4.4ns; (3) supply voltage minimum is 2V vs. 1.65V. Select 74LCX86MTCX only if the reduced temperature range and slower timing are acceptable.
Q: Are SN74LVC86AQPWRG4Q1 and SN74LVC86AQPWRQ1 interchangeable?
A: Yes. Both are AEC-Q100 qualified automotive-grade variants with identical electrical specifications. The difference is in packaging format: SN74LVC86AQPWRG4Q1 and SN74LVC86AQPWRQ1 are both supplied in Tape & Reel format. Verify packaging requirements with your procurement process.
Q: Why does the original 74LVC86APW,112 have higher quiescent current than the substitutes?
A: The original part specifies 40 µA maximum quiescent current. Texas Instruments SN74LVC86 variants specify 1 µA, representing improved process technology. This is a beneficial characteristic for power-sensitive applications.
Q: Can I use 74LCX86MTCX in a design requiring -40°C to 125°C operation?
A: No. 74LCX86MTCX is rated only to 85°C maximum. Use SN74LVC86APW, SN74LVC86APWR, or automotive-qualified variants (SN74LVC86AQPWRG4Q1, SN74LVC86AQPWRQ1) for extended temperature applications.
Q: Are all substitutes RoHS3 compliant?
A: All listed substitutes are RoHS3 compliant and REACH unaffected, matching the compliance status of the original part.
