Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74AS86ADG4 is based on the following critical parameters:

• Logic Function: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Electrical Specifications: Supply voltage 4.5V ~ 5.5V, output current 2mA/20mA, input logic levels 0.8V (low) and 2V (high), propagation delay 7.5ns @ 5V with 50pF load
• Operating Temperature Range: 0°C ~ 70°C
• Package Format: 14-SOIC surface mount package with 0.154" (3.90mm) width
• Compliance: ROHS3 compliant, MSL Level 1

The SN74AS86AD qualifies as a direct substitute because it maintains identical electrical performance, logic configuration, and package specifications while offering active product status.

Parameter Comparison

Engineering Selection Recommendations

The SN74AS86AD is the qualified substitute for the SN74AS86ADG4. Both parts share identical electrical specifications, logic configuration, and package format. The primary distinction is product status: the SN74AS86ADG4 is discontinued, while the SN74AS86AD maintains active status with current inventory availability.

Both parts are ROHS3 compliant and carry MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. Selection of the SN74AS86AD eliminates obsolescence risk while maintaining full functional and electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the SN74AS86AD directly replace the SN74AS86ADG4 in existing designs?

A: Yes. Both parts are electrically and mechanically identical, with matching supply voltage, output current, input logic levels, propagation delay, operating temperature range, and 14-SOIC package specifications.

Q: What is the difference between SN74AS86ADG4 and SN74AS86AD?

A: The primary difference is packaging format. The SN74AS86ADG4 uses DG4 packaging (tape and reel), while the SN74AS86AD uses tube packaging. Electrical and functional specifications are identical.

Q: Why is the SN74AS86ADG4 discontinued?

A: The SN74AS86ADG4 is discontinued at DiGi Electronics. The SN74AS86AD remains in active production and is the recommended alternative for new designs and replacements.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance and MSL Level 1 rating. REACH status is unaffected for both variants.

Q: What is the operating temperature range for these parts?

A: Both the SN74AS86ADG4 and SN74AS86AD operate across 0°C to 70°C, suitable for commercial and industrial applications within this thermal envelope.

Q: Can I use these parts interchangeably in high-speed logic circuits?

A: Yes, provided your circuit operates within the specified supply voltage (4.5V ~ 5.5V) and propagation delay requirements (7.5ns @ 5V, 50pF load). Both parts meet identical timing specifications.
