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 IC features open-drain outputs and operates across a wide supply voltage range of 2.5V to 11V (single supply) or ±1.25V to 5.5V (dual supply). The device is packaged in a 16-SOIC surface-mount configuration with a 3.90mm width.

The MAX974ESE is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production, maintenance, and new design implementations. Active substitute parts maintain identical electrical and mechanical specifications while offering current availability and extended product lifecycle support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of 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
• Supply Voltage Range: 2.5V ~ 11V (single) or ±1.25V ~ 5.5V (dual)
• Input Offset Voltage: 10mV maximum at 5V
• Quiescent Current: 8.5µA maximum
• Common-Mode and Power Supply Rejection: 80dB CMRR and 80dB PSRR
• Operating Temperature Range: -40°C to 85°C
• Package Specification: 16-SOIC with 3.90mm width
• Surface Mount Compatibility: Identical PCB footprint and mounting requirements
• Regulatory Compliance: ROHS3 compliance and MSL Level 1

The MAX974ESE+ is a direct substitute that maintains all electrical and mechanical parameters while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The MAX974ESE+ is the direct functional equivalent for the obsolete MAX974ESE. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical specifications and 16-SOIC package geometry.

Selection of the MAX974ESE+ is appropriate for:

• Replacement of existing MAX974ESE components in active production
• New designs requiring quad comparator functionality with integrated voltage reference
• Applications requiring open-drain output configuration
• Systems operating within the -40°C to 85°C temperature range
• Designs requiring ROHS3 compliance and MSL Level 1 moisture sensitivity rating

The primary distinction between the parts is product lifecycle status: the MAX974ESE is obsolete while the MAX974ESE+ maintains active manufacturing status. The MAX974ESE+ is supplied in tube packaging, which is standard for active production components.

Frequently Asked Questions (FAQ)

Q: Can the MAX974ESE+ be used as a direct replacement for the MAX974ESE?

A: Yes. The MAX974ESE+ is electrically and mechanically identical to the MAX974ESE. Both parts feature the same quad comparator architecture with integrated voltage reference, open-drain outputs, supply voltage range, input offset specifications, quiescent current, and 16-SOIC package configuration. The primary difference is product status: MAX974ESE+ is active while MAX974ESE is obsolete.

Q: Are there any PCB layout or footprint differences between these parts?

A: No. Both the MAX974ESE and MAX974ESE+ use the identical 16-SOIC package with 3.90mm width. PCB footprints, trace routing, and component placement require no modification when substituting between these parts.

Q: What is the significance of the "+" designation in the MAX974ESE+ part number?

A: The "+" suffix indicates the active production variant of the base MAX974 comparator series. This designation reflects current manufacturing status and packaging format (tube) while maintaining full electrical and mechanical compatibility with the obsolete MAX974ESE.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the MAX974ESE and MAX974ESE+ are ROHS3 compliant with MSL Level 1 moisture sensitivity rating, indicating unlimited shelf life under standard storage conditions.

Q: What supply voltage configurations are supported?

A: Both parts support single-supply operation from 2.5V to 11V or dual-supply operation from ±1.25V to 5.5V, providing flexibility for various circuit topologies and power distribution architectures.
