MAX907ESA Equivalent & Substitute Parts

Part Overview

The MAX907ESA is a dual general-purpose comparator manufactured by Analog Devices Inc./Maxim Integrated, packaged in 8-SOIC surface mount configuration. This device features TTL output logic and operates across a 4.5V to 11V supply voltage range. The MAX907ESA is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts must maintain functional compatibility through matching electrical characteristics and identical package geometry.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX907ESA is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package geometry: 8-SOIC (0.154", 3.90mm Width) — mandatory for PCB compatibility
• Number of comparator elements: 2 — functional requirement
• Mounting type: Surface Mount — assembly process compatibility
• Supply voltage range: Must encompass or overlap with 4.5V ~ 11V
• Output logic type: TTL or compatible logic family
• Operating temperature range: Must support -40°C ~ 85°C minimum

Substitute Parts Identified:

1. MAX907ESA+ — Direct equivalent from same manufacturer, active product status, identical electrical specifications and package, RoHS3 compliant
2. LMV762QMA/NOPB — Texas Instruments alternative, push-pull output, narrower supply range (2.7V ~ 5V), superior input offset and bias specifications, automotive grade with AEC-Q100 qualification
3. LMV762QMAX/NOPB — Texas Instruments alternative, identical specifications to LMV762QMA/NOPB, tape & reel packaging option, automotive grade with AEC-Q100 qualification

Engineering Selection Recommendations

MAX907ESA+ (Recommended Primary Substitute)

The MAX907ESA+ is the direct functional equivalent from the original manufacturer. It maintains identical electrical specifications, supply voltage range, and TTL output characteristics. The primary advantage is active product status with RoHS3 compliance, addressing obsolescence while preserving design compatibility. This part requires no circuit modifications and is suitable for direct replacement in existing designs.

LMV762QMA/NOPB and LMV762QMAX/NOPB (Alternative Substitutes)

The LMV762 series from Texas Instruments provides active product status with enhanced electrical performance. These parts feature superior input offset voltage (0.2mV vs. 2mV), lower input bias current (50pA vs. 0.3µA), and extended operating temperature range (-40°C to 125°C). The push-pull output topology differs from TTL output, requiring circuit evaluation for compatibility. The narrower supply voltage range (2.7V ~ 5V) restricts use in applications requiring voltages above 5V. Automotive-grade qualification (AEC-Q100) makes these parts suitable for automotive applications. LMV762QMAX/NOPB offers tape & reel packaging for high-volume production.

Compliance Considerations

MAX907ESA+ and LMV762 variants are RoHS3 compliant, addressing regulatory requirements for new designs. The original MAX907ESA is RoHS non-compliant and should be replaced in applications subject to RoHS directives.

Frequently Asked Questions (FAQ)

Q: Can MAX907ESA+ be used as a direct drop-in replacement for MAX907ESA?

A: Yes. MAX907ESA+ maintains identical electrical specifications, supply voltage range (4.5V ~ 11V), TTL output logic, and 8-SOIC package geometry. No circuit modifications are required.

Q: What are the key differences between MAX907ESA and LMV762 series comparators?

A: The LMV762 series features push-pull output instead of TTL, narrower supply voltage range (2.7V ~ 5V vs. 4.5V ~ 11V), superior input offset voltage and bias current specifications, and extended operating temperature range. Propagation delay is longer (225ns vs. 50ns). Circuit evaluation is required before substitution.

Q: Can LMV762QMA/NOPB be used in applications requiring supply voltages above 5V?

A: No. The LMV762 series maximum supply voltage is 5V. Applications requiring 11V operation must use MAX907ESA or MAX907ESA+.

Q: What is the difference between LMV762QMA/NOPB and LMV762QMAX/NOPB?

A: Both parts have identical electrical specifications and performance. The primary difference is packaging: LMV762QMA/NOPB is supplied in tube packaging, while LMV762QMAX/NOPB is supplied in tape & reel format for automated assembly.

Q: Are the LMV762 variants suitable for automotive applications?

A: Yes. Both LMV762QMA/NOPB and LMV762QMAX/NOPB carry automotive-grade qualification (AEC-Q100), making them suitable for automotive circuit designs.

Q: What is the impact of output type difference (TTL vs. Push-Pull) on circuit compatibility?

A: TTL and push-pull outputs have different electrical characteristics and load driving capabilities. Circuit evaluation is required to confirm compatibility. Existing designs optimized for TTL output may require modifications for push-pull operation.

Q: Is RoHS compliance a factor in selecting a substitute?

A: Yes, for applications subject to RoHS directives. MAX907ESA+ and LMV762 variants are RoHS3 compliant. The original MAX907ESA is non-compliant and should be replaced in regulated applications.
