MM74HC86N XOR Logic IC - Equivalent & Substitute Parts

Part Overview

The MM74HC86N is a 4-channel, 2-input XOR (Exclusive OR) logic integrated circuit manufactured by onsemi in 14-MDIP packaging. This component implements exclusive OR logic functions across four independent channels and operates across a 2V to 6V supply voltage range. The MM74HC86N is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM74HC86N are identified based on strict equivalence across the following critical parameters:

• Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Voltage Supply Range: 2V ~ 6V
• Current Specifications: Quiescent current 2 µA maximum; output current 5.2mA for both high and low states
• Input Logic Levels: Low 0.5V ~ 1.8V; High 1.5V ~ 4.2V
• Mounting Type: Through Hole
• Package: 14-DIP form factor (0.300", 7.62mm)
• Base Product Series: 74HC86

All identified substitutes maintain these core electrical and mechanical parameters, ensuring direct functional replacement in existing circuit designs.

Engineering Selection Recommendations

CD74HC86E (Harris Corporation): This substitute maintains identical electrical specifications and operating temperature range to the MM74HC86N. However, the CD74HC86E is classified as obsolete and RoHS non-compliant. Selection of this part is appropriate only when legacy component compatibility is required and RoHS compliance is not a design constraint.

SN74HC86N (Texas Instruments): This substitute is the preferred alternative for new designs and ongoing procurement. The SN74HC86N maintains all core electrical parameters and offers an extended operating temperature range (-55°C ~ 125°C). Critically, the SN74HC86N carries Active product status and ROHS3 compliance, making it suitable for applications requiring current manufacturing support and regulatory compliance. The propagation delay specification (17ns) is superior to the original part (20ns), providing improved performance margins.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC86N directly replace the MM74HC86N in existing designs?

A: Yes. The SN74HC86N maintains all critical electrical parameters: 4-channel XOR logic, 2V to 6V supply voltage, identical input/output current specifications, and 14-DIP through-hole packaging. The superior propagation delay (17ns vs 20ns) and extended temperature range provide additional design margin.

Q: What is the difference between the CD74HC86E and SN74HC86N?

A: Both parts are functionally equivalent in core logic operation. The primary differences are product status (both obsolete vs active), RoHS compliance (non-compliant vs ROHS3 compliant), and temperature range (CD74HC86E extends to -55°C ~ 125°C). For new designs, the SN74HC86N is recommended due to active manufacturing status and compliance certifications.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use 14-DIP (0.300", 7.62mm) through-hole packaging with identical pin configurations for the 74HC86 logic function.

Q: Does the propagation delay difference between parts affect circuit performance?

A: The SN74HC86N (17ns) offers faster propagation than the MM74HC86N (20ns). In most applications, this represents improved performance. Designs with timing-critical paths may benefit from this specification improvement.

Q: What compliance considerations apply to part selection?

A: The SN74HC86N is ROHS3 compliant and carries Active product status, making it suitable for applications requiring regulatory compliance and ongoing manufacturer support. The MM74HC86N and CD74HC86E are both obsolete; the CD74HC86E is additionally RoHS non-compliant.
