LMV762MMX Equivalent & Substitute Parts

Part Overview

The LMV762MMX is a dual-channel general-purpose comparator manufactured by Texas Instruments, housed in an 8-VSSOP surface-mount package. This device operates across a 2.7V to 5V supply range with push-pull output configuration, designed for precision signal comparison applications requiring low input offset voltage and high common-mode rejection.

The LMV762MMX carries a Last Time Buy product status, indicating discontinued production. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure long-term component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution logic for the LMV762MMX is based on the following critical parameters:

Parametric Equivalents (LMV762MM/NOPB, LMV762MMX/NOPB): These parts share identical electrical specifications, package type, and pin configuration. They differ only in packaging format (Tape & Reel vs. bulk) and product status (Active vs. Last Time Buy). These are direct functional replacements with no design modifications required.

Manufacturer-Recommended Alternatives (MAX997ESA+, MAX997EUA+T, TC75S57FU): These parts are recommended by Texas Instruments as functional alternatives but introduce design trade-offs:

MAX997 series: Single-channel comparator (vs. dual-channel), CMOS/TTL output (vs. push-pull), reduced operating temperature range (-40°C to 85°C vs. 125°C), different package footprints
TC75S57FU: Single-channel comparator, 5-SSOP package (vs. 8-VSSOP), wider supply voltage range (1.8V ~ 7V), different electrical characteristics

Substitution feasibility depends on application requirements for channel count, output type, temperature range, and package compatibility.

Engineering Selection Recommendations

Direct Replacement (No Design Changes Required): LMV762MM/NOPB and LMV762MMX/NOPB are parametric equivalents to the LMV762MMX. Both maintain identical electrical performance and package compatibility. Selection between these parts depends on packaging format availability and inventory status. LMV762MMX/NOPB offers higher inventory (20,245 pcs) compared to LMV762MM/NOPB (18,298 pcs), both in Active product status.

Conditional Substitution (Design Review Required): MAX997ESA+ and MAX997EUA+T are manufacturer-recommended alternatives suitable only for applications where single-channel operation is acceptable. These parts introduce reduced CMRR/PSRR performance (80dB/86.02dB vs. 100dB/110dB), higher input offset voltage (1.5mV vs. 0.2mV), and restricted operating temperature range (-40°C to 85°C vs. 125°C). MAX997EUA+T maintains 8-TSSOP package compatibility; MAX997ESA+ uses 8-SOIC package requiring PCB layout modification.

TC75S57FU(TE85L,F) is a single-channel alternative with 5-SSOP package, incompatible with 8-VSSOP footprints. This part offers superior input bias current (1pA) and lower quiescent current (220µA) but exhibits significantly higher input offset voltage (7mV) and lacks CMRR/PSRR specifications. Temperature range limitation to 85°C applies.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can LMV762MM/NOPB and LMV762MMX/NOPB be used interchangeably with LMV762MMX?

A: Yes. These parts are parametric equivalents with identical electrical specifications, pin configuration, and package dimensions. The differences are packaging format (Tape & Reel vs. bulk) and product status (Active vs. Last Time Buy). No circuit modifications are required.

Q: What are the key limitations when substituting MAX997 series comparators?

A: MAX997 series parts are single-channel devices, reducing functionality by 50% compared to the dual-channel LMV762MMX. Additionally, they feature CMOS/TTL output instead of push-pull, higher input offset voltage (1.5mV vs. 0.2mV), reduced CMRR/PSRR performance, and maximum operating temperature of 85°C instead of 125°C. Applications requiring dual-channel operation or extended temperature range cannot use these parts.

Q: Is the TC75S57FU(TE85L,F) a viable substitute?

A: TC75S57FU is not recommended as a direct substitute due to package incompatibility (5-SSOP vs. 8-VSSOP), single-channel configuration, and significantly higher input offset voltage (7mV). It is suitable only for new designs where package footprint and channel count can be accommodated.

Q: What is the difference between 8-SOIC and 8-TSSOP packages?

A: 8-SOIC (0.154", 3.90mm width) and 8-TSSOP (0.118", 3.00mm width) are physically different packages with distinct PCB footprints. MAX997ESA+ uses 8-SOIC, requiring PCB layout redesign. MAX997EUA+T uses 8-TSSOP, maintaining footprint compatibility with LMV762MMX.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. LMV762MM/NOPB, LMV762MMX/NOPB, MAX997ESA+, MAX997EUA+T, and TC75S57FU(TE85L,F) are all ROHS3 compliant with MSL Level 1 rating, matching the original LMV762MMX specifications.

Q: What should be considered when selecting between available LMV762 variants?

A: Selection criteria include inventory availability, packaging format (Tape & Reel vs. bulk), and lead time. LMV762MMX/NOPB offers the highest inventory (20,245 pcs) in Active status. For applications requiring immediate availability, this variant is preferred. All LMV762 variants maintain identical electrical performance and package compatibility.
