Key Parameters

Substitute Part Grouping Explanation

Substitution of the GAL16V8D-15LP is determined by the following critical parameters:

• Macrocell Count: 8 macrocells (functional logic capacity)
• Speed Grade: 15 ns propagation delay (timing performance)
• Package Type: 20-DIP (0.300", 7.62mm) (physical and electrical interface)
• Programmable Type: EE PLD (electrically erasable programmable logic device)
• Pin Configuration: 20-pin DIP (pinout compatibility)

The ATF16V8B-15PU meets all substitution criteria. Both devices share identical macrocell count, speed grade, package dimensions, and programmable technology, ensuring functional and physical compatibility in applications requiring the GAL16V8D-15LP.

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8B-15PU is the direct functional equivalent for the GAL16V8D-15LP. Selection between these devices should be based on the following factors:

For Legacy System Maintenance: The GAL16V8D-15LP remains available in inventory (6990 pcs) and is suitable for direct replacement in existing applications where the original device specification is required.

For New Designs and Long-Term Support: The ATF16V8B-15PU is recommended. This device is in active production status with significantly higher inventory availability (24212 pcs), ensuring supply chain continuity. The ATF16V8B-15PU offers improved compliance certifications (ROHS3 Compliant versus RoHS non-compliant) and superior moisture sensitivity characteristics (MSL 1 versus MSL 3), reducing handling and storage risks.

Both devices share identical electrical specifications (8 macrocells, 15 ns speed, 5V operation) and physical form factor (20-DIP), ensuring pin-for-pin compatibility and functional interchangeability in circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can the ATF16V8B-15PU directly replace the GAL16V8D-15LP in existing circuits?

A: Yes. Both devices are functionally equivalent with identical macrocell count (8), speed grade (15 ns), and 20-DIP package configuration. Pin-for-pin substitution is supported without circuit modification.

Q: What is the primary difference between these two devices?

A: The GAL16V8D-15LP is obsolete and manufactured by Lattice Semiconductor, while the ATF16V8B-15PU is an active product from Microchip Technology. The ATF16V8B-15PU offers improved RoHS compliance and lower moisture sensitivity, making it preferable for new designs.

Q: Are there any compatibility concerns with package type?

A: No. Both devices use the 20-DIP (0.300", 7.62mm) package with through-hole mounting. Physical and electrical interfaces are identical.

Q: Which device should be selected for new product development?

A: The ATF16V8B-15PU is recommended for new designs due to active product status, higher inventory availability, and superior compliance certifications.

Q: Are both devices electrically erasable programmable logic devices?

A: Yes. Both the GAL16V8D-15LP and ATF16V8B-15PU are EE PLD devices, supporting electrical erasure and reprogramming cycles.
