ATF750C-7SC Equivalent & Substitute Parts

Part Overview

The ATF750C-7SC is a Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology, featuring 10 macrocells and 10 I/O pins with a maximum propagation delay of 7.5 ns. This device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and production requirements. The ATF750C-7SC operates within a 4.75V to 5.25V supply voltage range and is housed in a 24-SOIC surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF750C-7SC is determined by strict equivalence across the following critical parameters:

• Device Architecture: EE PLD with identical macrocell and I/O configuration (10 macrocells, 10 I/O)
• Electrical Performance: Propagation delay of 7.5 ns maximum
• Power Supply Compatibility: 4.75V to 5.25V internal supply voltage
• Package Compatibility: 24-SOIC surface mount package with identical physical dimensions (0.295", 7.50mm width)
• Temperature Range: 0°C to 70°C operating specification
• Manufacturer: Microchip Technology ATF750 series

The ATF750C-7SX meets all substitution criteria as a direct functional equivalent within the ATF750C(L) series.

Parameter Comparison

Engineering Selection Recommendations

The ATF750C-7SX is the direct substitute for the obsolete ATF750C-7SC. Both devices share identical electrical specifications, performance characteristics, and physical packaging. The primary distinction is product lifecycle status: the ATF750C-7SC is obsolete while the ATF750C-7SX maintains active production status.

The ATF750C-7SX provides improved compliance posture with ROHS3 certification, whereas the ATF750C-7SC is RoHS non-compliant. The moisture sensitivity level differs (MSL 3 versus MSL 1), reflecting standard handling requirements for active production components. These differences do not affect functional equivalence or electrical interchangeability in circuit applications.

Selection of the ATF750C-7SX is appropriate for new designs and production continuity where the ATF750C-7SC is no longer available.

Frequently Asked Questions (FAQ)

Q: Are the ATF750C-7SC and ATF750C-7SX electrically interchangeable?

A: Yes. Both devices are electrically identical with matching macrocell count (10), I/O configuration (10 pins), propagation delay (7.5 ns maximum), and supply voltage range (4.75V to 5.25V).

Q: Can the ATF750C-7SX be used as a direct replacement in existing PCB designs?

A: Yes. The ATF750C-7SX uses the identical 24-SOIC package with matching physical dimensions (0.295", 7.50mm width) and surface mount configuration. No PCB layout modifications are required.

Q: What is the difference in RoHS compliance between these parts?

A: The ATF750C-7SC is RoHS non-compliant. The ATF750C-7SX is ROHS3 compliant. This distinction affects regulatory compliance for end-product applications but does not impact electrical functionality or performance.

Q: Why does the ATF750C-7SX have a higher moisture sensitivity level (MSL 3)?

A: MSL classification reflects handling and storage requirements for active production components. MSL 3 (168 hours) is standard for modern surface mount devices. This does not affect device performance or reliability in properly managed supply chain conditions.

Q: Is the ATF750C-7SC still available for purchase?

A: The ATF750C-7SC is classified as obsolete. The ATF750C-7SX is the active production equivalent and is the recommended source for new procurement.
