Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF750LVC-15PC is determined by strict equivalence across the following parameters:

• Programmable Logic Architecture: EE PLD technology with identical macrocell and I/O count (10 macrocells, 10 I/O pins)
• Propagation Delay: Maximum 15 nanosecond tpd(1) specification
• Physical Package: 24-DIP through-hole form factor with 0.300" (7.62mm) pitch
• Electrical Compatibility: Voltage supply range and operating temperature envelope must accommodate the original design requirements
• Manufacturer Consistency: Microchip Technology ATF750LVC series maintains functional and pinout compatibility

The ATF750LVC-15PU qualifies as a direct substitute based on matching all core electrical and mechanical parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ATF750LVC-15PU is the qualified substitute for the obsolete ATF750LVC-15PC. Selection criteria are based on the following factors:

Product Status: The ATF750LVC-15PU maintains active product status with verified programmability through Microchip Technology, whereas the ATF750LVC-15PC is classified as obsolete. Active status ensures continued availability and manufacturing support.

Compliance Certifications: The ATF750LVC-15PU achieves ROHS3 compliance, meeting current environmental and regulatory requirements. The ATF750LVC-15PC is RoHS non-compliant, presenting potential restrictions in regulated markets and supply chain applications.

Electrical Envelope: The ATF750LVC-15PU provides an extended voltage supply range (3V ~ 5.5V versus 3V ~ 5.25V) and expanded operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C), offering greater design flexibility and environmental tolerance without compromising core functional specifications.

Functional Equivalence: Both devices maintain identical macrocell count, I/O configuration, propagation delay specification, and physical package format, ensuring direct functional substitution in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the ATF750LVC-15PU directly replace the ATF750LVC-15PC in existing designs?

A: Yes. Both devices share identical programmable logic architecture (10 macrocells, 10 I/O), propagation delay (15 ns maximum), and 24-DIP package format. The ATF750LVC-15PU provides extended electrical and temperature specifications, making it functionally compatible with designs originally specified for the ATF750LVC-15PC.

Q: What is the primary difference between these two part numbers?

A: The ATF750LVC-15PC is obsolete with RoHS non-compliant status, while the ATF750LVC-15PU is an active product with ROHS3 compliance. The ATF750LVC-15PU also offers wider voltage supply range (3V ~ 5.5V) and extended operating temperature range (-40°C ~ 85°C).

Q: Are there packaging differences between ATF750LVC-15PC and ATF750LVC-15PU?

A: Both devices use identical 24-DIP through-hole packaging with 0.300" (7.62mm) pitch. The primary packaging difference is the supplier device format: the ATF750LVC-15PC uses standard DIP packaging, while the ATF750LVC-15PU is supplied in tube packaging. Pin configuration and mechanical dimensions remain identical.

Q: Does the extended temperature range of the ATF750LVC-15PU affect compatibility?

A: No. The extended operating temperature range (-40°C ~ 85°C) of the ATF750LVC-15PU is a superset of the original specification (0°C ~ 70°C). Designs operating within the original temperature envelope remain fully compatible.

Q: What compliance advantages does the ATF750LVC-15PU provide?

A: The ATF750LVC-15PU achieves ROHS3 compliance and maintains REACH Unaffected status, meeting current environmental regulations. This eliminates potential supply chain restrictions and regulatory compliance issues associated with the RoHS non-compliant ATF750LVC-15PC.
