ATF16V8BQ-10PC Equivalent & Substitute Parts

Part Overview

The ATF16V8BQ-10PC is a 16V8 Programmable Logic Device (PLD) IC featuring 8 macrocells, designed for through-hole mounting in 20-DIP packages. This component operates at 5V input with a 10 ns propagation delay. The part is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATF16V8BQ-10PC is determined by the following critical parameters:

• Series Compatibility: All substitute parts must belong to the 16V8 series
• Macrocell Count: Substitute parts must have 8 macrocells
• Programmable Type: EE PLD technology must be maintained
• Input Voltage: 5V operation is required
• Package Specification: 20-DIP (0.300", 7.62mm) / 20-PDIP form factor is mandatory
• Mounting Type: Through-hole mounting must be preserved

The identified substitute parts meet all these criteria. Speed variations (propagation delay) are acceptable within the 16V8 architecture, as faster devices maintain backward compatibility with designs specified for slower speeds.

Parameter Comparison

Engineering Selection Recommendations

ATF16V8B-15PU is suitable for applications where the 15 ns propagation delay meets timing requirements. This part carries Active product status and ROHS3 compliance, providing long-term availability and regulatory alignment. Inventory availability is substantial at 24,212 pieces.

ATF16V8C-7PU offers superior speed performance at 7.5 ns propagation delay, providing timing margin for designs originally specified for 10 ns operation. This part is also Active status with ROHS3 compliance. Inventory is available at 1,900 pieces. The faster speed characteristic ensures compatibility with the original ATF16V8BQ-10PC specification while providing enhanced performance headroom.

Both substitute parts eliminate the obsolescence risk associated with the ATF16V8BQ-10PC and provide compliance with current environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can ATF16V8B-15PU replace ATF16V8BQ-10PC in existing designs?

A: Yes. The ATF16V8B-15PU maintains identical macrocell count, input voltage, package form factor, and mounting type. The 15 ns speed specification is slower than the original 10 ns, so timing analysis must confirm that the design's critical path does not exceed 15 ns propagation delay.

Q: Is ATF16V8C-7PU a direct substitute?

A: Yes. The ATF16V8C-7PU provides all required functional and mechanical compatibility. The 7.5 ns speed is faster than the original specification, ensuring timing compatibility with designs specified for 10 ns operation.

Q: What is the difference between the substitute parts?

A: The primary difference is propagation delay: ATF16V8B-15PU operates at 15 ns while ATF16V8C-7PU operates at 7.5 ns. Both parts are electrically and mechanically compatible with the original ATF16V8BQ-10PC. Selection depends on the timing requirements of the specific application.

Q: Are the substitute parts available in the same packaging?

A: Yes. Both substitute parts are supplied in 20-PDIP packages with identical 0.300" (7.62mm) pitch, ensuring direct board-level compatibility without layout modifications.

Q: What compliance advantages do the substitute parts offer?

A: Both ATF16V8B-15PU and ATF16V8C-7PU are ROHS3 compliant, whereas the original ATF16V8BQ-10PC is RoHS non-compliant. This provides regulatory compliance for new designs and production runs.
