CD74HCT86M XOR Logic IC Equivalent & Substitute Parts

Part Overview

The CD74HCT86M is a 4-channel, 2-input XOR (Exclusive OR) logic gate integrated circuit manufactured by Texas Instruments in a 14-SOIC surface mount package. This part is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement. The 74HCT86 logic family provides standard TTL-compatible XOR functionality across multiple manufacturers and packaging options, enabling direct functional replacement in applications requiring this logic operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HCT86M is determined by strict equivalence across the following critical parameters:

• Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Voltage Supply Range: 4.5V ~ 5.5V nominal operation
• Output Drive Capability: 4mA high and low
• Input Logic Thresholds: 0.8V low, 2V high
• Propagation Delay: 32ns maximum at specified conditions
• Package Compatibility: 14-SOIC surface mount form factor
• Compliance: ROHS3, MSL 1, REACH Unaffected

All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional and physical interchangeability in the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

CD74HCT86M96 (Texas Instruments) is the primary recommended substitute. It maintains identical electrical specifications and operating temperature range (-55°C ~ 125°C) as the original CD74HCT86M, with the advantage of active product status and higher inventory availability (15,664 units). Packaging is available in Cut Tape and Digi-Reel formats.

MC74HCT86ADR2G (onsemi) offers superior performance characteristics with lower quiescent current (1 µA vs. 2 µA), faster propagation delay (20ns vs. 32ns), and extended voltage supply range (2V ~ 6V). This part is suitable for applications requiring enhanced performance margins and is available in active status with 9,261 units in stock.

74HCT86D,653 (Nexperia USA Inc.) and 74HCT86D-Q100,118 (Nexperia USA Inc.) are functionally equivalent alternatives with active product status. The 74HCT86D-Q100,118 variant includes AEC-Q100 automotive qualification, making it appropriate for automotive-grade applications. Both Nexperia parts operate across -40°C ~ 125°C temperature range, which is narrower than the original specification.

74HCT86S14-13 (Diodes Incorporated) is available in high volume (30,200 units) with active status. This part exhibits higher quiescent current (20 µA) compared to the original specification (2 µA), which may impact power consumption in battery-operated or low-power applications.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory and environmental compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can I use CD74HCT86M96 as a direct replacement for CD74HCT86M?

A: Yes. CD74HCT86M96 is functionally and electrically equivalent to CD74HCT86M. Both are manufactured by Texas Instruments, share identical electrical specifications, and operate across the same temperature range (-55°C ~ 125°C). The primary difference is product status: CD74HCT86M96 is active with higher inventory availability.

Q: What is the difference between 14-SOIC and 14-SO packages?

A: Both designations refer to 14-pin surface mount packages with 0.154" (3.90mm) width. The packages are mechanically and electrically compatible for PCB assembly and circuit operation. Verify footprint compatibility with your PCB design documentation.

Q: Is MC74HCT86ADR2G compatible with my existing circuit?

A: MC74HCT86ADR2G is electrically compatible with CD74HCT86M for standard 5V logic applications. However, it offers enhanced specifications: lower quiescent current (1 µA vs. 2 µA), faster propagation delay (20ns vs. 32ns), and wider voltage supply range (2V ~ 6V). These improvements provide additional design margin and are backward compatible with existing 4.5V ~ 5.5V supply circuits.

Q: Why does 74HCT86S14-13 have higher quiescent current?

A: 74HCT86S14-13 (Diodes Incorporated) specifies 20 µA maximum quiescent current compared to 2 µA for the original CD74HCT86M. This difference reflects manufacturing process variations between suppliers. For applications with strict power consumption requirements, verify that the higher quiescent current is acceptable for your design.

Q: Can I use 74HCT86D-Q100,118 in non-automotive applications?

A: Yes. 74HCT86D-Q100,118 is AEC-Q100 qualified for automotive use but is fully functional in standard industrial and commercial applications. The automotive qualification represents an additional quality assurance level and does not restrict use in other applications.

Q: What is the operating temperature difference between substitutes?

A: CD74HCT86M and CD74HCT86M96 operate across -55°C ~ 125°C. Nexperia parts (74HCT86D,653 and 74HCT86D-Q100,118) and Diodes Incorporated part (74HCT86S14-13) operate across -40°C ~ 125°C. If your application requires operation below -40°C, select CD74HCT86M96 or MC74HCT86ADR2G.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level and REACH unaffected status, matching the original CD74HCT86M compliance profile.
