Key Parameters

Substitute Part Grouping Explanation

Substitution for the ATF16V8B-10PI is determined by strict equivalence in the following parameters:

• Series: 16V8
• Number of Macrocells: 8
• Voltage - Input: 5V
• Mounting Type: Through Hole
• Package / Case: 20-DIP (0.300", 7.62mm)
• Programmable Type: EE PLD

Speed (propagation delay) is a performance parameter that allows substitution with equal or faster devices. The ATF16V8B-10PI operates at 10 ns; devices with 15 ns or 7.5 ns speed ratings maintain functional compatibility while offering different performance characteristics. Both identified substitute parts meet all core electrical and mechanical compatibility requirements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products from Microchip Technology and maintain full electrical and mechanical compatibility with the ATF16V8B-10PI. Selection between substitutes depends on application requirements and regulatory compliance:

ATF16V8B-15PU is suitable for applications where the 15 ns propagation delay meets timing requirements. This device is ROHS3 compliant and represents a direct speed-relaxed alternative to the obsolete ATF16V8B-10PI.

ATF16V8C-7PU offers superior speed performance at 7.5 ns propagation delay, providing margin for timing-critical applications. This device is also ROHS3 compliant and is recommended for new designs requiring enhanced performance characteristics.

Both substitute parts are available in active production status, ensuring supply chain continuity and long-term availability compared to the obsolete main part number.

Frequently Asked Questions (FAQ)

Q: Can ATF16V8B-15PU be used as a direct replacement for ATF16V8B-10PI?

A: Yes. The ATF16V8B-15PU maintains identical electrical specifications (5V input, 8 macrocells, EE PLD type) and physical package (20-DIP). The 15 ns speed rating is slower than the original 10 ns specification but provides functional compatibility for applications where this timing margin is acceptable.

Q: What is the primary advantage of ATF16V8C-7PU over ATF16V8B-15PU?

A: The ATF16V8C-7PU provides faster propagation delay at 7.5 ns compared to 15 ns, offering improved performance for timing-sensitive applications. Both devices are electrically and mechanically compatible with the ATF16V8B-10PI.

Q: Are there any package differences between these parts?

A: No. All three parts use identical 20-DIP (0.300", 7.62mm) through-hole packaging, ensuring direct PCB compatibility without layout modifications.

Q: Why is the ATF16V8B-10PI listed as obsolete?

A: The ATF16V8B-10PI has been discontinued by Microchip Technology. Both substitute parts are active products, providing continued availability and support for applications requiring 16V8 PLD functionality.

Q: Do the substitute parts meet current regulatory requirements?

A: Yes. Both ATF16V8B-15PU and ATF16V8C-7PU are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The original ATF16V8B-10PI is RoHS non-compliant.
