SN74LVC86APWE4 Equivalent & Substitute Parts

Part Overview

The SN74LVC86APWE4 is a 4-channel 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 design support and production requirements. The device operates across a 1.65V to 3.6V supply voltage range with low quiescent current and is suitable for low-voltage digital logic applications requiring XOR functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74LVC86APWE4 is determined by the following critical parameters: logic type (XOR, 4-channel, 2-input configuration), package type (14-TSSOP surface mount), supply voltage compatibility, output current capability (24mA minimum), and operating temperature range. Parts are grouped into two categories:

MFR Recommended Substitutes maintain full electrical and mechanical compatibility with the original part, including identical or superior supply voltage ranges, quiescent current specifications, and propagation delay characteristics.

Parametric Equivalents share the same logic function and package but may have minor variations in electrical performance within acceptable operating margins.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SN74LVC86APW

The SN74LVC86APW from Texas Instruments is the direct active substitute. It maintains identical electrical specifications to the SN74LVC86APWE4, including supply voltage range (1.65V ~ 3.6V), quiescent current (1 µA), and propagation delay (4.4ns @ 3.3V, 50pF). Both parts are ROHS3 compliant with MSL 1 rating. The primary difference is packaging format (Tube vs. the original TSSOP variant), which does not affect electrical performance or PCB compatibility.

Secondary Recommendation: 74LVC86APW,118

The 74LVC86APW,118 from Nexperia USA Inc. is an active substitute with extended lower supply voltage capability (1.2V ~ 3.6V) and maintains the full -40°C to 125°C operating temperature range. Quiescent current is higher at 40 µA and propagation delay is 5ns, representing acceptable performance trade-offs for applications not requiring the lowest power consumption. ROHS3 compliant with MSL 1 rating.

Alternative Consideration: 74LCX86MTCX and MC74LCX86DTR2G

Both the Fairchild 74LCX86MTCX and onsemi MC74LCX86DTR2G are functionally equivalent XOR logic gates in 14-TSSOP packages. These parts operate within 2V ~ 3.6V supply range, limiting use in applications requiring 1.65V operation. Operating temperature range is restricted to -40°C ~ 85°C. Quiescent current is 10 µA and propagation delay is 6.5ns. These substitutes are suitable for standard industrial temperature applications where the lower voltage threshold is acceptable.

Parametric Equivalent: SN74LVC86APWG4

The SN74LVC86APWG4 is a parametric equivalent with identical electrical specifications to the original part but is also discontinued at DiGi Electronics. This part should not be considered for new designs or production restocking.

Frequently Asked Questions (FAQ)

Q: Can I use 74LCX86MTCX as a direct replacement for SN74LVC86APWE4?

A: The 74LCX86MTCX is functionally compatible in the same 14-TSSOP package and performs the same XOR logic function. However, it has a minimum supply voltage of 2V versus 1.65V for the original part. If your application operates at voltages below 2V, this substitute is not suitable. Additionally, the operating temperature range is limited to -40°C ~ 85°C compared to -40°C ~ 125°C for the original.

Q: What is the difference between SN74LVC86APW and 74LVC86APW,118?

A: Both are 4-channel XOR logic gates in 14-TSSOP packages from different manufacturers (Texas Instruments vs. Nexperia). The SN74LVC86APW has lower quiescent current (1 µA vs. 40 µA) and faster propagation delay (4.4ns vs. 5ns). The 74LVC86APW,118 supports lower minimum supply voltage (1.2V vs. 1.65V). Select based on power consumption and voltage requirements of your application.

Q: Are all substitute parts ROHS3 compliant?

A: The SN74LVC86APW, 74LVC86APW,118, and MC74LCX86DTR2G are confirmed ROHS3 compliant. The 74LCX86MTCX from Fairchild Semiconductor does not list ROHS status in the provided specifications. Verify compliance requirements with your procurement or quality department before selection.

Q: Can I use these parts interchangeably on the same PCB?

A: All substitute parts use the 14-TSSOP package with identical pin configuration and footprint. PCB layout compatibility is assured. However, verify that your circuit design accommodates the electrical parameter variations, particularly supply voltage range, quiescent current, and propagation delay specifications of the selected substitute.

Q: What is the MSL (Moisture Sensitivity Level) for these parts?

A: The SN74LVC86APW, 74LVC86APW,118, and MC74LCX86DTR2G all have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The 74LCX86MTCX does not specify MSL in the provided data. Parts with MSL 1 require no special moisture control during storage or handling.
