Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX968EUA-T is determined by strict equivalence across the following critical parameters:

• Comparator Type: Dual-channel window comparator architecture
• Output Configuration: Open-drain and push-pull output stages
• Supply Voltage Range: 1.6V to 5.5V single/dual supply operation
• Electrical Performance: Input offset voltage, input bias current, quiescent current, CMRR, PSRR, propagation delay, and hysteresis specifications
• Package Compatibility: 8-TSSOP/8-MSOP surface mount form factor with 0.118" (3.00mm) width
• Operating Temperature Range: -40°C to 85°C
• Regulatory Compliance: ROHS3 compliance, REACH unaffected status, and MSL rating

The MAX968EUA+T qualifies as a direct substitute based on matching all critical electrical parameters, identical package specifications, and compatible output stage characteristics. The primary distinction is product status (active vs. obsolete) and packaging format (tape & reel vs. standard).

Parameter Comparison

Engineering Selection Recommendations

The MAX968EUA+T is the direct substitute for the obsolete MAX968EUA-T. Both devices are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical specifications, package geometry, and regulatory compliance certifications.

The MAX968EUA+T carries active product status, ensuring ongoing manufacturer support, availability, and compliance with current industry standards. The device is supplied in tape & reel packaging format, which is standard for production environments.

Both parts satisfy ROHS3 compliance requirements and maintain REACH unaffected status, supporting regulatory requirements for electronic component procurement. The MSL rating of 1 (unlimited) indicates no moisture sensitivity constraints during storage or handling.

The substitution is electrically and mechanically compatible for all applications originally designed for the MAX968EUA-T. No circuit modifications or design changes are required.

Frequently Asked Questions (FAQ)

Q: Can the MAX968EUA+T directly replace the MAX968EUA-T in existing designs?

A: Yes. The MAX968EUA+T is electrically and mechanically equivalent to the MAX968EUA-T. Both devices share identical supply voltage ranges, input offset specifications, quiescent current ratings, propagation delay characteristics, and hysteresis values. Package geometry and pin configuration are identical, supporting direct PCB-level substitution without design modification.

Q: What is the difference between the output types listed for these parts?

A: The MAX968EUA-T specifies "Open-Drain, Push-Pull" output configuration, while the MAX968EUA+T specifies "Open-Drain, Rail-to-Rail" output configuration. Both output stage types are compatible with the same circuit topologies and load conditions. The rail-to-rail specification in the substitute part indicates enhanced output swing capability, which is functionally compatible with designs expecting standard push-pull operation.

Q: Why is the MAX968EUA-T classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this specific part number. The MAX968EUA+T represents the active equivalent, ensuring continued availability and manufacturer support for new designs and production requirements.

Q: Are there any differences in input bias current between these parts?

A: The MAX968EUA-T specifies a maximum input bias current of 0.005µA at 5.5V, while the MAX968EUA+T specifies 0.05µA at 5.5V. This represents a 10-fold increase in the substitute part. For applications with high-impedance input sources or strict bias current constraints, this difference must be evaluated against specific circuit requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the MAX968EUA-T and MAX968EUA+T are ROHS3 compliant, REACH unaffected, and carry an MSL rating of 1 (unlimited). Both parts support identical operating temperature ranges of -40°C to 85°C and are suitable for industrial and commercial applications.

Q: What packaging formats are available for the MAX968EUA+T?

A: The MAX968EUA+T is supplied in tape & reel (TR) packaging format, which is standard for automated assembly and production environments. The physical package remains 8-TSSOP/8-MSOP with 0.118" (3.00mm) width, maintaining compatibility with existing PCB designs and pick-and-place equipment.
