MAX907ESA-T Equivalent & Substitute Parts

Part Overview

The MAX907ESA-T is a dual general-purpose comparator manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-SOIC surface mount package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The MAX907ESA-T operates across a 4.5V to 11V supply range with TTL output configuration, suitable for general-purpose comparison applications requiring moderate speed performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX907ESA-T is determined by the following critical parameters: dual-element comparator configuration, 8-SOIC package footprint, surface mount mounting type, and compliance certifications (ROHS3, REACH Unaffected). The substitute parts are grouped into two categories:

Parametric Equivalent: Parts maintaining identical electrical specifications and product lineage within the same manufacturer family.

Manufacturer Recommended Alternatives: Parts from different manufacturers offering comparable or enhanced performance characteristics while maintaining package compatibility and compliance requirements.

The key substitution criteria are:

• Dual comparator elements (2 channels)
• 8-SOIC package form factor
• Surface mount configuration
• ROHS3 and REACH compliance
• Operating temperature range compatibility
• Supply voltage overlap

Engineering Selection Recommendations

MAX907ESA+T (Parametric Equivalent): This part is the direct active equivalent from Analog Devices Inc./Maxim Integrated. It maintains identical electrical specifications, supply voltage range (4.5V ~ 11V), TTL output configuration, and operating temperature range (-40°C ~ 85°C). The MAX907ESA+T is currently in active production status with significantly higher inventory availability (45,300 pcs) compared to the obsolete MAX907ESA-T. This part is the preferred choice for direct replacement in existing designs without circuit modification.

LMV762QMA/NOPB and LMV762QMAX/NOPB (Manufacturer Recommended Alternatives): These Texas Instruments parts offer enhanced performance characteristics including superior input offset voltage (0.2mV vs. 2mV), lower input bias current (50pA vs. 0.3µA), and improved CMRR/PSRR specifications (100dB/110dB vs. 86.02dB). Both parts feature AEC-Q100 automotive qualification and extended operating temperature range (-40°C ~ 125°C). The trade-offs are narrower supply voltage range (2.7V ~ 5V vs. 4.5V ~ 11V), longer propagation delay (225ns vs. 50ns), and Push-Pull output configuration instead of TTL. These alternatives are suitable for applications where the narrower supply range and slower propagation delay are acceptable, and where the enhanced precision and automotive qualification provide system benefits.

Frequently Asked Questions (FAQ)

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

A: Yes. The MAX907ESA+T is electrically and mechanically identical to the MAX907ESA-T. Both parts share the same 8-SOIC package footprint, supply voltage range (4.5V ~ 11V), TTL output type, and operating temperature specifications. The primary difference is product status: MAX907ESA+T is active production while MAX907ESA-T is obsolete.

Q: What are the key differences between MAX907ESA+T and LMV762 series parts?

A: The MAX907ESA+T maintains TTL output configuration and 4.5V ~ 11V supply range, while LMV762 series parts feature Push-Pull outputs and operate on 2.7V ~ 5V supplies. LMV762 parts offer superior precision (0.2mV input offset vs. 2mV) and lower input bias current (50pA vs. 0.3µA), but have longer propagation delay (225ns vs. 50ns). LMV762 parts include AEC-Q100 automotive qualification and extended temperature range (-40°C ~ 125°C).

Q: Are the LMV762QMA/NOPB and LMV762QMAX/NOPB parts interchangeable?

A: Both parts are electrically identical. The difference is packaging: LMV762QMA/NOPB is supplied in Tube packaging, while LMV762QMAX/NOPB is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and volume needs.

Q: What supply voltage range must be considered when substituting with LMV762 parts?

A: LMV762 series parts operate on 2.7V ~ 5V supplies, which is narrower than the MAX907ESA-T range of 4.5V ~ 11V. If the application requires supply voltages above 5V or below 4.5V, LMV762 parts are not suitable. The MAX907ESA+T must be used in such cases.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All listed substitute parts (MAX907ESA+T, LMV762QMA/NOPB, LMV762QMAX/NOPB) are ROHS3 compliant, REACH unaffected, and have MSL rating of 1 (Unlimited). The LMV762 series additionally carries AEC-Q100 automotive qualification.

Q: What is the impact of output type differences (TTL vs. Push-Pull)?

A: TTL outputs (MAX907ESA-T, MAX907ESA+T) are optimized for TTL logic compatibility with specific pull-up characteristics. Push-Pull outputs (LMV762 series) provide active drive capability in both high and low states. Circuit design must account for these differences in output impedance and loading characteristics.
