Engineering Selection Recommendations
Primary Substitutes (Direct Replacement):
SN74LVC86AD, SN74LVC86ADR, and SN74LVC86ADT from Texas Instruments are the preferred direct substitutes. All three maintain the 1.65V ~ 3.6V supply voltage range, identical propagation delay characteristics, and the required 14-SOIC (3.90mm) package footprint. These parts are active products with established supply availability and full RoHS3 compliance.
Extended Temperature Range Option:
SN74LVC86AMDREP extends the operating temperature range to -55°C ~ 125°C, suitable for applications requiring enhanced low-temperature performance. This part maintains the 14-SOIC (3.90mm) package and active product status.
Automotive Grade Option:
SN74LVC86AQDRG4Q1 is qualified to AEC-Q100 automotive standards with active product status. This variant is appropriate for automotive and high-reliability applications requiring formal qualification documentation.
Wider Supply Voltage Range:
74LVC86AS14-13 from Diodes Incorporated offers the widest supply voltage range (1.65V ~ 5.5V) while maintaining the required package and performance specifications. This part is suitable for applications requiring operation across extended voltage domains.
Alternative Series:

Frequently Asked Questions (FAQ)
Q: Can I use SN74LVC86ANS or SN74LVC86ANSR as direct replacements for the 74LVC86AD,112?
A: These parts are functionally equivalent but have a different package width (5.30mm vs. 3.90mm). While the pin count and logic function are identical, the physical footprint differs. PCB layout compatibility must be verified before substitution.
Q: What is the difference between the various Texas Instruments SN74LVC86 variants?
A: The variants differ primarily in packaging format (tube, tape & reel, cut tape) and supply voltage specifications. SN74LVC86AD, SN74LVC86ADR, and SN74LVC86ADT all support 1.65V ~ 3.6V and are electrically identical. The SN74LVC86AQDREP and SN74LVC86AQDRG4Q1 variants have a narrower supply range (2V ~ 3.6V) but lower quiescent current. SN74LVC86AMDREP extends the temperature range to -55°C.
Q: Is the 74LVC86AS14-13 from Diodes Incorporated compatible with my 3.3V application?
A: Yes. The 74LVC86AS14-13 supports 1.65V ~ 5.5V supply voltage, which encompasses the 3.3V operating point. The part maintains identical logic function, output current capability, and 14-SOIC (3.90mm) package footprint as the original 74LVC86AD,112.
Q: Why does the MC74LCX86DR2G have a lower maximum operating temperature?
A: The MC74LCX86DR2G is specified for -40°C ~ 85°C operation, which is 40°C lower than the 74LVC86 series maximum. This part is suitable for standard industrial applications but should not be used in applications requiring the full -40°C ~ 125°C range.
Q: What is the significance of the AEC-Q100 qualification on the SN74LVC86AQDRG4Q1?
A: AEC-Q100 qualification indicates the part meets automotive industry reliability and quality standards. This variant is appropriate for automotive applications and systems requiring formal qualification documentation, though it maintains the same electrical performance as other 74LVC86 variants.
Q: Can I substitute the 74LVC86AD,112 with MC74LCX86DR2G in a -40°C to 125°C application?
A: No. The MC74LCX86DR2G is specified only to 85°C maximum operating temperature. For applications requiring full -40°C ~ 125°C operation, use Texas Instruments SN74LVC86 variants or the Diodes Incorporated 74LVC86AS14-13.
