SN74AC86PWE4 Equivalent & Substitute Parts

Part Overview

The SN74AC86PWE4 is a 4-channel XOR (Exclusive OR) logic gate IC manufactured by Texas Instruments in 14-TSSOP surface mount packaging. This component is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and production requirements. The 74AC86 series provides standard logic gating functionality across a wide supply voltage range of 2V to 6V, suitable for digital logic applications requiring XOR operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74AC86PWE4 is determined by strict equivalence across the following critical parameters: logic type (XOR, 4-channel, 2-input configuration), supply voltage range (2V ~ 6V), output current capability (24mA), propagation delay (8.5ns @ 5V, 50pF), operating temperature range (-40°C ~ 85°C), and 14-TSSOP package format. All substitute parts listed maintain these electrical and mechanical specifications, ensuring functional and physical compatibility within the same circuit design.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production continuity, the 74AC86MTCX (Fairchild Semiconductor) and MC74AC86DTR2G (onsemi) are preferred substitutes due to their active product status and full compliance with RoHS3 standards. The SN74AC86PW (Texas Instruments) remains available as a Last Time Buy option and maintains identical electrical specifications with ROHS3 compliance. The 74AC86MTC (Fairchild Semiconductor) provides an alternative with active status; however, complete parameter specifications are not provided in the available data. All listed substitutes maintain the 14-TSSOP package format and core XOR logic functionality required for direct circuit board replacement.

Frequently Asked Questions (FAQ)

Q: Can the 74AC86MTCX replace the SN74AC86PWE4 directly on the PCB? A: Yes. Both parts share identical 14-TSSOP surface mount packaging, pin configuration, and electrical specifications (supply voltage 2V ~ 6V, 24mA output current, 8.5ns propagation delay). Direct substitution is supported without circuit modification.

Q: What is the difference between the SN74AC86PW and SN74AC86PWE4? A: Both are Texas Instruments 74AC86 XOR logic gates with identical electrical specifications. The primary difference is packaging format: SN74AC86PW is supplied in Tube packaging, while SN74AC86PWE4 uses a different supplier device package designation. The SN74AC86PW is designated Last Time Buy status.

Q: Why does the MC74AC86DTR2G show 4 µA quiescent current instead of 2 µA? A: The MC74AC86DTR2G (onsemi) specifies a maximum quiescent current of 4 µA compared to 2 µA for other variants. This remains within acceptable operating parameters for XOR logic applications and does not affect functional compatibility or logic performance.

Q: Are all substitute parts RoHS3 compliant? A: The SN74AC86PWE4, SN74AC86PW, and MC74AC86DTR2G are confirmed ROHS3 compliant. RoHS compliance status is not specified for the 74AC86MTCX and 74AC86MTC variants in the available data.

Q: What packaging options are available for 74AC86 substitutes? A: Available packaging formats include 14-TSSOP Bulk (74AC86MTCX, 74AC86MTC), 14-TSSOP Tube (SN74AC86PW), and 14-TSSOP Tape & Reel (MC74AC86DTR2G). All maintain the same 0.173" width, 4.40mm physical dimensions for PCB compatibility.
