Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HCT86D,652 is determined by strict equivalence across the following critical parameters:

• Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Package / Case: 14-SOIC (0.154", 3.90mm Width) for mechanical and electrical pin compatibility
• Voltage Supply Range: Minimum 4.5V ~ 5.5V overlap required
• Input/Output Logic Levels: 0.8V (Low) and 2V (High) compatibility
• Output Current Capability: 4mA minimum for both High and Low states
• Propagation Delay: 32ns maximum at specified conditions
• Compliance: ROHS3 and REACH Unaffected status maintained

Substitute parts are grouped into two categories: Upgrade parts (active or recently discontinued with full parameter compatibility) and Similar parts (active alternatives with enhanced or equivalent performance characteristics).

Parameter Comparison

Engineering Selection Recommendations

CD74HCT86M96 (Texas Instruments) is the primary upgrade substitute. This part maintains identical electrical specifications to the original 74HCT86D,652 while offering active product status and extended lower operating temperature range (-55°C vs. -40°C). The part is available in Cut Tape and Digi-Reel packaging with substantial inventory (15,664 units). Full ROHS3 compliance and REACH Unaffected status are maintained.

CD74HCT86MT (Texas Instruments) provides equivalent electrical performance with identical parameter specifications. This part is discontinued at DiGi Electronics but remains available through alternative distribution channels. It is suitable for applications where Tape & Reel packaging is required and inventory availability is confirmed.

MC74HCT86ADR2G (onsemi) is a compatible alternative with enhanced performance characteristics. This part offers a wider supply voltage range (2V ~ 6V), lower quiescent current (1 µA vs. 2 µA), and faster propagation delay (20ns vs. 32ns). Extended lower operating temperature (-55°C) and active product status support long-term design continuity. All compliance certifications match the original specification.

All substitute parts maintain mechanical compatibility through identical 14-SOIC packaging and electrical compatibility through matching logic levels, output current capability, and functional operation as 4-channel, 2-input XOR gates.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT86M96 be used as a direct replacement for 74HCT86D,652?

A: Yes. Both parts share identical electrical specifications including voltage supply range (4.5V ~ 5.5V), input/output logic levels, output current (4mA), and propagation delay (32ns @ 4.5V, 50pF). The 14-SOIC package is mechanically and electrically compatible. CD74HCT86M96 offers extended lower operating temperature range (-55°C vs. -40°C) and active product status.

Q: What is the difference between CD74HCT86M96 and CD74HCT86MT?

A: Both parts are manufactured by Texas Instruments with identical electrical specifications. The primary difference is packaging format: CD74HCT86M96 is supplied in Cut Tape and Digi-Reel format, while CD74HCT86MT is supplied in Tape & Reel format. CD74HCT86M96 has higher current inventory availability (15,664 units vs. 1,168 units).

Q: Why does MC74HCT86ADR2G have different propagation delay specifications?

A: MC74HCT86ADR2G achieves 20ns propagation delay at 5V with 50pF load, compared to 32ns for the original part at 4.5V with 50pF load. This represents improved performance at higher supply voltage. The part remains functionally compatible as a 4-channel, 2-input XOR gate with matching logic levels and output current capability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (CD74HCT86M96, CD74HCT86MT, and MC74HCT86ADR2G) maintain ROHS3 compliance and REACH Unaffected status, matching the original 74HCT86D,652 specification.

Q: Can MC74HCT86ADR2G operate at the original supply voltage range of 4.5V ~ 5.5V?

A: Yes. MC74HCT86ADR2G supports a wider supply voltage range of 2V ~ 6V, which fully encompasses the original 4.5V ~ 5.5V specification. The part is fully compatible with existing circuit designs operating within the original voltage range.

Q: What is the moisture sensitivity level for all substitute parts?

A: All substitute parts maintain Moisture Sensitivity Level 1 (Unlimited), identical to the original 74HCT86D,652. This indicates no moisture sensitivity restrictions for storage or handling.
