Engineering Selection Recommendations

For applications requiring direct replacement of the CD74HC86MG4, select from active production parts with matching or superior electrical characteristics and full temperature range support.

MC74HC86ADG (onsemi) and MC74HC86ADR2G (Fairchild Semiconductor) are preferred substitutes. Both maintain the 14-SOIC package, support the full -55°C to 125°C temperature range, and deliver improved propagation delay (17ns versus 20ns). Quiescent current is reduced to 1 µA, providing lower power consumption. Both parts are in active production with high inventory availability.

74HC86D,653 (Nexperia USA Inc.) is a direct functional equivalent in 14-SO package with identical electrical specifications. Operating temperature is limited to -40°C to 125°C. This part is actively produced with 2,700 units in stock.

74HC86D-Q100,118 (Nexperia USA Inc.) is the automotive-qualified variant of the above part, certified to AEC-Q100 standard. This variant is suitable for automotive and high-reliability applications requiring formal qualification documentation.

MM74HC86M and MM74HC86MX (Fairchild Semiconductor) are active alternatives in 14-SOIC package with identical electrical performance to the original part. Operating temperature range is restricted to -40°C to 85°C, making these suitable only for commercial and industrial applications not requiring extended low-temperature operation.

For applications with relaxed temperature requirements (-40°C to 85°C), 74HC86S14-13 (Diodes Incorporated) offers the fastest propagation delay at 15ns with 47,800 units in stock, providing superior performance and supply security.

Obsolete parts (CD74HC86M, NLV74HC86ADG, NLV74HC86ADR2G) should be avoided for new designs due to discontinued status and limited inventory.

Frequently Asked Questions (FAQ)

Q: Can MC74HC86ADG replace CD74HC86MG4 directly?

A: Yes. MC74HC86ADG is a direct functional substitute. Both are 4-channel XOR logic ICs in 14-SOIC package with 2V to 6V supply range and -55°C to 125°C operating temperature. MC74HC86ADG offers improved propagation delay (17ns versus 20ns) and lower quiescent current (1 µA versus 2 µA). Pin configuration and logic function are identical.

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. SOIC and SO are equivalent package types used interchangeably by different manufacturers.

Q: Are the Nexperia 74HC86D variants suitable for my application?

A: Nexperia 74HC86D,653 and 74HC86D-Q100,118 are functionally equivalent to the original part with identical electrical specifications. The primary difference is operating temperature range (-40°C to 125°C versus -55°C to 125°C). If your application operates above -40°C, these parts are fully suitable. The Q100 variant includes automotive qualification; use this only if AEC-Q100 certification is required.

Q: Why do some substitutes have lower quiescent current?

A: MC74HC86ADG and onsemi NLV variants specify 1 µA quiescent current versus 2 µA for the original part. This reflects manufacturing process improvements and tighter specifications. Lower quiescent current reduces power consumption in standby conditions and is a beneficial characteristic for battery-powered or low-power applications.

Q: Can I use MM74HC86MX if my application requires -55°C operation?

A: No. MM74HC86MX is rated only to -40°C minimum. For applications requiring -55°C operation, use MC74HC86ADG, MC74HC86ADR2G, or the automotive-qualified NLV variants, all of which support the full -55°C to 125°C range.

Q: What does AEC-Q100 qualification mean?

A: AEC-Q100 is an automotive industry standard qualification for integrated circuits. 74HC86D-Q100,118 and NLV74HC86ADG/ADR2G carry this certification, indicating the parts meet automotive reliability and quality requirements. Use these variants only if your application requires formal automotive qualification documentation.

Q: Is RoHS3 compliance important for my selection?

A: RoHS3 compliance indicates the part contains no restricted hazardous substances. Most active production parts listed (74HC86D variants, MC74HC86ADG, NLV variants) are RoHS3 compliant. Verify compliance status if your application or region requires it.
