74LVX86MX XOR Logic IC Equivalent & Substitute Parts

Part Overview

The 74LVX86MX is a 4-channel, 2-input XOR (Exclusive OR) logic gate IC manufactured by onsemi in a 14-SOIC surface mount package. This part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74LVX86MX operates at low voltage levels (2V to 3.6V) with minimal quiescent current consumption, suitable for battery-powered and portable applications requiring XOR logic functionality.

Substitute Part Grouping Explanation

Substitution for the 74LVX86MX is determined by the following critical parameters: logic type (XOR, 4-channel, 2-input configuration), package type (14-SOIC surface mount), supply voltage compatibility, quiescent current specifications, output drive capability, propagation delay performance, and operating temperature range.

Substitute parts are grouped into two categories:

Parametric Equivalent: MC74LVX86DR2G maintains identical electrical specifications and voltage range (2V ~ 3.6V) as the main part, differing only in packaging format (Tape & Reel vs. Cut Tape).

Similar Parts: SN74AHC86DR, SN74LV86AD, SN74LV86ADR, and SN74LV86ANSR provide XOR logic functionality with the same circuit and input configuration but operate across wider voltage ranges (2V ~ 5.5V) and feature different quiescent current, output drive, and propagation delay characteristics. These parts maintain the same 14-SOIC package footprint (with SN74LV86ANSR in a wider 14-SO variant) and are suitable where the expanded voltage range and performance parameters align with application requirements.

Parameter Comparison

Engineering Selection Recommendations

MC74LVX86DR2G is the direct parametric equivalent for the 74LVX86MX. Both parts maintain identical electrical specifications across voltage supply, quiescent current, output drive capability, and propagation delay. The primary difference is packaging format (Tape & Reel vs. Cut Tape). This part is currently in active production status and is the preferred direct replacement.

SN74AHC86DR provides XOR logic functionality with expanded voltage range (2V ~ 5.5V) and improved propagation delay (8.8ns vs. 12.8ns). This part is suitable for applications requiring higher voltage operation or faster switching performance. Operating temperature extends to 125°C. Output drive capability is doubled (8mA vs. 4mA). This part is in active production status.

SN74LV86ADR and SN74LV86AD are functionally equivalent Texas Instruments alternatives with expanded voltage range (2V ~ 5.5V), higher quiescent current (20 µA vs. 2 µA), and increased output drive (12mA vs. 4mA). SN74LV86ADR is in active production; SN74LV86AD is discontinued at DiGi Electronics. These parts are suitable where higher output drive capability is required and quiescent current is not a limiting factor.

SN74LV86ANSR provides identical electrical performance to SN74LV86ADR but in a wider 14-SO package (5.30mm vs. 3.90mm width). This part is in active production and is suitable only where the wider package footprint is compatible with PCB layout requirements.

All substitute parts maintain ROHS3 compliance and are suitable for applications requiring XOR logic functionality with the specified circuit and input configuration.

Frequently Asked Questions (FAQ)

Q: Can MC74LVX86DR2G be used as a direct replacement for 74LVX86MX?

A: Yes. MC74LVX86DR2G is a parametric equivalent with identical electrical specifications. The only difference is packaging format (Tape & Reel vs. Cut Tape). Both parts operate at 2V ~ 3.6V supply voltage with 2 µA quiescent current and 12.8ns propagation delay at 3.3V.

Q: What is the key difference between 74LVX86MX and SN74AHC86DR?

A: SN74AHC86DR operates across a wider voltage range (2V ~ 5.5V vs. 2V ~ 3.6V), features faster propagation delay (8.8ns vs. 12.8ns), and provides higher output drive capability (8mA vs. 4mA). Quiescent current remains at 2 µA. SN74AHC86DR is suitable for applications requiring higher voltage operation or improved switching speed.

Q: Why do SN74LV86ADR and SN74LV86AD have higher quiescent current?

A: The 74LV series is designed with different internal architecture compared to the 74LVX series, resulting in higher quiescent current (20 µA vs. 2 µA). However, these parts provide higher output drive capability (12mA vs. 4mA) and operate across a wider voltage range (2V ~ 5.5V).

Q: Is SN74LV86ANSR compatible with the same PCB footprint as 74LVX86MX?

A: No. SN74LV86ANSR uses a wider 14-SO package (5.30mm width) compared to the standard 14-SOIC package (3.90mm width) used by 74LVX86MX. This part requires PCB layout modification and is suitable only where the wider package footprint can be accommodated.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (MC74LVX86DR2G, SN74AHC86DR, SN74LV86AD, SN74LV86ADR, and SN74LV86ANSR) are ROHS3 compliant and suitable for applications requiring environmental compliance.

Q: Which substitute part has the best availability?

A: MC74LVX86DR2G (3382 Pcs in stock) and SN74LV86ANSR (6799 Pcs in stock) have the highest current inventory levels. SN74LV86ADR (2000 Pcs) and SN74AHC86DR (3350 Pcs) also maintain active stock levels.
