MAX907CSA Equivalent & Substitute Parts

Part Overview

The MAX907CSA is a general-purpose dual comparator IC manufactured by Analog Devices Inc./Maxim Integrated in 8-SOIC surface mount packaging. This device features TTL output configuration with a supply voltage range of 4.5V to 11V and propagation delay of 50ns maximum. The MAX907CSA 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.

Substitute Part Grouping Explanation

Substitution for the MAX907CSA is determined by the following critical parameters: package geometry (8-SOIC), number of comparator elements (2), output configuration (TTL or compatible), supply voltage compatibility, and propagation delay performance. The MAX907CSA+ serves as a direct equivalent with identical electrical specifications but improved RoHS3 compliance and active product status. The LMV762 series (LMV762QMA/NOPB and LMV762QMAX/NOPB) represents functional alternatives with push-pull output configuration, lower supply voltage range (2.7V ~ 5V), superior input offset voltage (0.2mV), and automotive-grade qualification (AEC-Q100). These substitutes maintain the same 8-SOIC package and dual-element configuration but operate within a narrower supply voltage window and feature extended temperature range (-40°C ~ 125°C).

Engineering Selection Recommendations

The MAX907CSA+ is the preferred direct substitute, offering identical electrical performance and pinout compatibility while providing active product status and ROHS3 compliance. This part is suitable for designs requiring the original TTL output configuration and 4.5V to 11V supply voltage range.

The LMV762QMA/NOPB and LMV762QMAX/NOPB represent functional alternatives for applications where supply voltage can be constrained to 2.7V to 5V. These parts offer superior input offset voltage specification (0.2mV versus 2mV), lower input bias current (50pA versus 0.3µA), and extended operating temperature range (-40°C to 125°C). The trade-off is increased propagation delay (225ns versus 50ns) and push-pull output configuration instead of TTL. Both LMV762 variants carry AEC-Q100 automotive qualification and ROHS3 compliance. Selection between LMV762QMA/NOPB (Tube packaging) and LMV762QMAX/NOPB (Tape & Reel packaging) depends on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX907CSA+ be used as a direct replacement for MAX907CSA?

A: Yes. The MAX907CSA+ maintains identical electrical specifications, pinout, and 8-SOIC package geometry. The primary differences are active product status and ROHS3 compliance, making it a direct functional equivalent.

Q: What are the key differences between MAX907CSA and LMV762 series comparators?

A: The LMV762 series differs in three critical areas: output type (push-pull versus TTL), supply voltage range (2.7V–5V versus 4.5V–11V), and propagation delay (225ns versus 50ns). The LMV762 offers superior input offset voltage and input bias current specifications, plus extended temperature range and automotive qualification.

Q: Can LMV762QMA/NOPB replace MAX907CSA in a 5V single-supply application?

A: Functional replacement is possible if the application tolerates 225ns propagation delay and push-pull output characteristics. The LMV762QMA/NOPB operates within the 2.7V–5V range and maintains the same 8-SOIC package. Circuit-level verification is required to confirm output drive capability and timing compatibility.

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

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

Q: Are all substitute parts RoHS compliant?

A: MAX907CSA is RoHS non-compliant. MAX907CSA+, LMV762QMA/NOPB, and LMV762QMAX/NOPB are all ROHS3 compliant, meeting current environmental regulations.

Q: Does the LMV762 series carry automotive qualification?

A: Yes. Both LMV762QMA/NOPB and LMV762QMAX/NOPB are AEC-Q100 qualified for automotive applications with extended temperature range (-40°C to 125°C).
