MAX974ESE+ Equivalent & Substitute Parts

Part Overview

The MAX974ESE+ is a quad comparator with integrated voltage reference, manufactured by Analog Devices Inc./Maxim Integrated. This linear integrated circuit operates as an open-drain output comparator suitable for precision voltage comparison applications across a wide supply voltage range. The device is currently in active production status with 713 units available in new original inventory. Alternative part identification becomes necessary for supply chain continuity, design flexibility, or inventory management in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX974ESE+ is determined by strict equivalence across the following critical parameters:

• Functional type: Quad comparator with integrated voltage reference
• Output configuration: Open-drain topology
• Package format: 16-SOIC surface mount
• Supply voltage range: 2.5V ~ 11V single supply, ±1.25V ~ 5.5V dual supply
• Input offset voltage: Maximum 10mV @ 5V
• Quiescent current: Maximum 8.5µA
• Common-mode and power-supply rejection: 80dB minimum for both CMRR and PSRR
• Operating temperature range: -40°C ~ 85°C
• Compliance certifications: ROHS3 and REACH requirements

Only parts meeting all specified parameters across electrical performance, package dimensions, and regulatory compliance qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The MAX974ESE+ maintains active production status with confirmed inventory availability. Component selection should prioritize parts with identical electrical specifications, matching 16-SOIC package geometry, and equivalent regulatory compliance certifications. ROHS3 compliance and MSL Level 1 rating ensure compatibility with standard manufacturing and storage protocols. The active product status provides long-term supply assurance for production applications.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX974ESE+? A: A valid substitute must match all specified electrical parameters including supply voltage range (2.5V ~ 11V single, ±1.25V ~ 5.5V dual), input offset voltage (10mV @ 5V maximum), quiescent current (8.5µA maximum), and rejection ratios (80dB CMRR and PSRR). The package must be 16-SOIC surface mount, and regulatory compliance must include ROHS3 and REACH requirements.

Q: Can the MAX974ESE+ be replaced with a different package type? A: No. The 16-SOIC package is a critical specification for PCB layout compatibility. Substitutes must use the identical 16-SOIC (0.154", 3.90mm Width) package format to ensure proper board integration without redesign.

Q: Is the open-drain output type essential for substitution? A: Yes. The open-drain output topology is fundamental to the device function and circuit interface requirements. Substitutes must maintain this output configuration.

Q: What is the significance of the 80dB CMRR and PSRR specifications? A: These rejection ratios determine the comparator's ability to reject common-mode signals and power supply noise. Substitutes must meet or exceed these specifications to maintain circuit performance and noise immunity.

Q: Does MSL Level 1 affect component handling? A: MSL Level 1 indicates unlimited shelf life without moisture sensitivity concerns, simplifying storage and handling procedures compared to higher MSL ratings. This specification should be maintained in substitute selection.
