74AC86MTC XOR Logic IC Equivalent & Substitute Parts

Part Overview

The 74AC86MTC is a 4-channel, 2-input XOR (Exclusive OR) logic integrated circuit manufactured by onsemi in 14-TSSOP surface mount packaging. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The 74AC86 series provides standard XOR gate functionality across the 74AC logic family, with multiple manufacturers and packaging options available to meet application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74AC86MTC is determined by strict equivalence in the following parameters: logic type (XOR), circuit count (4 channels), input count (2 inputs per gate), voltage supply range (2V–6V), operating temperature range (-40°C to 85°C), propagation delay (8.5ns @ 5V, 50pF), output current ratings (24mA), and RoHS3 compliance. Packaging differences between 14-TSSOP and 14-SSOP represent mechanical variations that may affect board layout but do not alter electrical functionality. Quiescent current variations within the specified range do not disqualify parts from substitution. Product status (active, last time buy, or obsolete) indicates availability but does not affect electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the obsolete 74AC86MTC in existing designs, SN74AC86PW (Texas Instruments, tube packaging) provides electrical equivalence with identical quiescent current and propagation delay specifications. Both parts use 14-TSSOP packaging, ensuring PCB footprint compatibility.

For new production designs or high-volume applications, SN74AC86PWR (Texas Instruments, active status, tape & reel) or MC74AC86DTR2G (onsemi, active status, tape & reel) are preferred due to active product status and standard manufacturing packaging. The MC74AC86DTR2G exhibits slightly elevated quiescent current (4 µA versus 2 µA) but remains within acceptable operational parameters and maintains all other electrical specifications.

SN74AC86DBR (Texas Instruments, 14-SSOP package) is electrically equivalent but uses a different package footprint (14-SSOP, 5.30mm width versus 14-TSSOP, 4.40mm width). This part requires PCB layout modification and is suitable only when package dimensions are not constrained.

All substitute parts maintain ROHS3 compliance and are rated for the same operating temperature range (-40°C to 85°C), ensuring regulatory and thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can MC74AC86DTR2G replace 74AC86MTC directly on the PCB?

A: Yes. Both parts use 14-TSSOP packaging with identical footprints. The quiescent current difference (4 µA versus 2 µA) does not affect circuit operation and remains within the 74AC logic family specifications.

Q: What is the difference between 14-TSSOP and 14-SSOP packages?

A: Both are surface mount packages with 14 pins. The 14-TSSOP (thin shrink small outline package) has a 4.40mm width, while 14-SSOP (shrink small outline package) has a 5.30mm width. PCB footprints are not interchangeable; design layout must accommodate the specific package type.

Q: Why is 74AC86MTC listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Active alternatives from onsemi (MC74AC86DTR2G) and Texas Instruments (SN74AC86PWR, SN74AC86PW) provide equivalent functionality and are recommended for new designs and ongoing procurement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: Can SN74AC86DBR be used as a substitute if PCB layout permits?

A: Yes. SN74AC86DBR is electrically equivalent and maintains all functional specifications. However, the 14-SSOP package requires PCB redesign compared to the 14-TSSOP footprint of the original 74AC86MTC.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging is used for lower-volume applications and manual assembly. Tape & reel packaging is standard for automated manufacturing and high-volume production. Electrical specifications are identical; packaging choice depends on assembly process requirements.
