SN74AHC86PW XOR Logic IC 4-Channel 2-Input Equivalent & Substitute Parts

Part Overview

The SN74AHC86PW is a 4-channel 2-input XOR (Exclusive OR) logic gate IC manufactured by Texas Instruments in a 14-TSSOP surface mount package. This part is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The XOR logic function with 4 independent channels serves as a fundamental building block in digital logic circuits requiring exclusive OR operations across multiple signal paths.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74AHC86PW is determined by strict equivalence across the following critical parameters:

• Logic function: 4-channel 2-input XOR gate
• Package type: 14-TSSOP surface mount
• Voltage supply range: 2V ~ 5.5V minimum
• Output current capability: 8mA minimum for both high and low states
• Propagation delay: 8.8ns @ 5V, 50pF maximum
• Operating temperature range: -40°C ~ 125°C minimum
• RoHS3 compliance and MSL 1 rating

Substitute parts are grouped into three categories based on manufacturer, product status, and availability. All listed substitutes maintain functional and electrical equivalence within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Direct Replacement): SN74AHC86PWR from Texas Instruments is the direct active equivalent. It maintains identical electrical specifications and operating temperature range as the original SN74AHC86PW, with the only difference being packaging format (Cut Tape & Digi-Reel versus Tube). This part is actively manufactured and widely available.

Alternative Active Substitutes:

74AHC86PW,118 from Nexperia USA Inc. provides full electrical and thermal equivalence with higher inventory availability (23025 Pcs). This part is actively produced and maintains the complete -40°C ~ 125°C operating range.

74AHC86T14-13 from Diodes Incorporated is functionally equivalent with identical propagation delay and output current specifications. The quiescent current specification differs (20 µA versus 2 µA), which may impact low-power applications. This part is actively manufactured.

Conditional Substitute: 74VHC86MTCX from onsemi is electrically equivalent but operates only to 85°C maximum, compared to 125°C for the original part. Use this substitute only in applications where the reduced upper temperature limit is acceptable. This part is actively produced with high inventory.

Not Recommended: NLVVHC86DTR2G from onsemi is obsolete and should not be selected for new designs despite extended temperature range (-55°C ~ 125°C). Obsolete status indicates discontinued manufacturing and limited future availability.

All recommended substitutes maintain RoHS3 compliance and MSL 1 rating consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can SN74AHC86PWR be used as a direct replacement for SN74AHC86PW?

A: Yes. SN74AHC86PWR is the direct active equivalent from Texas Instruments. All electrical parameters, operating temperature range, and logic specifications are identical. The difference is packaging format: SN74AHC86PWR is supplied in Cut Tape & Digi-Reel format rather than Tube. Both are 14-TSSOP surface mount packages with identical pinouts and footprints.

Q: What is the difference between 74AHC86PW,118 and SN74AHC86PWR?

A: Both parts are electrically identical with full parameter equivalence. The primary differences are manufacturer (Nexperia versus Texas Instruments) and packaging format. 74AHC86PW,118 has significantly higher inventory availability (23025 Pcs versus 6100 Pcs). Both are actively produced and suitable for new designs.

Q: Why does 74AHC86T14-13 have a higher quiescent current specification (20 µA versus 2 µA)?

A: The quiescent current difference reflects manufacturing variations between Diodes Incorporated and other manufacturers. While 74AHC86T14-13 meets all functional and timing specifications, the higher quiescent current may result in increased power consumption in standby conditions. Evaluate this parameter for battery-powered or low-power applications.

Q: Can 74VHC86MTCX be used in applications requiring operation above 85°C?

A: No. 74VHC86MTCX is specified for -40°C ~ 85°C operation only. The original SN74AHC86PW and most active substitutes operate to 125°C. Use 74VHC86MTCX only in applications where the maximum operating temperature does not exceed 85°C.

Q: Is NLVVHC86DTR2G suitable for new production designs?

A: No. NLVVHC86DTR2G is obsolete and no longer manufactured. While limited inventory exists (3248 Pcs), obsolete status indicates discontinued production and uncertain future availability. Select from active substitutes for new designs.

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

A: Yes. All listed substitutes use the 14-TSSOP (0.173", 4.40mm Width) surface mount package. Pinouts and footprints are identical, enabling direct PCB substitution without layout modifications.

Q: Do all substitutes maintain RoHS3 compliance?

A: Yes. All recommended active substitutes (SN74AHC86PWR, 74AHC86PW,118, 74AHC86T14-13, and 74VHC86MTCX) are RoHS3 compliant with MSL 1 rating, matching the original SN74AHC86PW specification.
