SN74AHC86D XOR Logic IC - Equivalent & Substitute Parts

Part Overview

The SN74AHC86D is a 4-channel, 2-input XOR (Exclusive OR) logic gate integrated circuit manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design requirements and production needs. The 74AHC86 logic family provides standard XOR functionality across multiple manufacturers with compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74AHC86D is determined by the following critical parameters that must remain constant across all equivalent parts:

• Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Voltage Supply Range: 2V ~ 5.5V
• Operating Temperature Range: -40°C ~ 125°C
• Package/Case: 14-SOIC form factor (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS3 Compliance and MSL Level 1 rating

The substitute parts listed below maintain these core specifications, allowing direct functional replacement in circuit designs. Variations in quiescent current, output current ratings, and packaging format (tube, cut tape, bulk, or tape & reel) do not affect electrical compatibility for standard XOR gate applications.

Parameter Comparison

Engineering Selection Recommendations

SN74AHC86DR (Texas Instruments) is the primary direct substitute for the discontinued SN74AHC86D. Both parts are manufactured by Texas Instruments with identical electrical specifications, including quiescent current (2 µA maximum) and propagation delay (8.8ns @ 5V, 50pF). The SN74AHC86DR maintains active product status and is available in cut tape and Digi-Reel packaging formats. This part is recommended for applications requiring continuity with the original design specifications.

74AHC86D,118 (NXP Semiconductors) provides an alternative from a different manufacturer while maintaining the 74AHC86 base product number and core functional compatibility. This part is available in bulk packaging and carries active product status. Detailed electrical parameters are not fully specified in the available data; verification against application requirements is necessary before selection.

74AHC86S14-13 (Diodes Incorporated) is a manufacturer-recommended alternative that maintains all critical electrical parameters including voltage supply range, operating temperature, and propagation delay. The quiescent current specification differs at 20 µA maximum compared to 2 µA for the original part. This part is available in tape & reel packaging with active product status and full RoHS3 compliance.

All substitute parts maintain the 14-SOIC package form factor, surface mount mounting type, and MSL Level 1 rating, ensuring mechanical and environmental compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can I use SN74AHC86DR as a direct replacement for SN74AHC86D?

A: Yes. The SN74AHC86DR is a direct electrical and mechanical equivalent. Both parts share identical specifications for logic type, channel count, input count, voltage supply range, operating temperature, package type, and output current ratings. The primary difference is packaging format (cut tape/Digi-Reel versus tube) and product status (active versus discontinued).

Q: What is the difference between the 14-SOIC and 14-SO packages used in these parts?

A: The 14-SOIC (Small Outline Integrated Circuit) and 14-SO (Small Outline) designations refer to the same physical package form factor with 0.154" (3.90mm) width. Both are surface mount packages compatible with standard PCB assembly equipment and footprints.

Q: Does the higher quiescent current of the 74AHC86S14-13 (20 µA) affect compatibility?

A: The 74AHC86S14-13 maintains functional compatibility for XOR logic operations. The increased quiescent current specification (20 µA versus 2 µA) may impact power consumption in battery-powered or low-power applications. Evaluate total system power requirements before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—SN74AHC86DR, 74AHC86D,118, and 74AHC86S14-13—carry ROHS3 compliance certification and MSL Level 1 rating, matching the environmental and regulatory status of the original SN74AHC86D.

Q: What packaging formats are available for these substitute parts?

A: SN74AHC86DR is available in cut tape and Digi-Reel formats. 74AHC86D,118 is supplied in bulk packaging. 74AHC86S14-13 is available in tape & reel format. Select the packaging format that matches your procurement and assembly workflow requirements.

Q: Can I mix different manufacturers' parts in the same production run?

A: All substitute parts maintain identical electrical specifications for logic function, voltage supply, operating temperature, and output characteristics. Mixing manufacturers is technically feasible; however, standard engineering practice recommends maintaining a single qualified source per design revision to ensure consistency in supply chain management and quality control.
