LMC6762BIMX Equivalent & Substitute Parts

Part Overview

The LMC6762BIMX is a dual general-purpose comparator manufactured by Texas Instruments, featuring push-pull, rail-to-rail output configuration in an 8-SOIC surface mount package. This device operates across a wide supply voltage range of 2.7V to 15V (single supply) or ±1.35V to ±7.5V (dual supply), making it suitable for analog signal comparison applications in industrial and consumer electronics.

The LMC6762BIMX is classified as obsolete, with limited inventory availability. Equivalent and substitute parts are necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements. Substitute devices must maintain functional compatibility across critical electrical parameters including supply voltage range, output type, and propagation delay characteristics.

Engineering Selection Recommendations

Direct Parametric Equivalent:

LMC6762BIMX/NOPB is the direct parametric equivalent with identical electrical specifications and 8-SOIC package compatibility. This part maintains active product status with significantly higher inventory availability (22,700 units) compared to the obsolete LMC6762BIMX. Selection of this part eliminates all compatibility concerns and requires no circuit redesign.

Manufacturer-Recommended Alternatives:

The following active parts are manufacturer-recommended substitutes suitable for general-purpose comparator applications where the LMC6762BIMX supply voltage range and output current specifications are not critical constraints:

MAX9032ASA+T and MAX9032AUA+ offer superior performance characteristics including faster propagation delay (228ns vs. 10µs), lower input offset voltage (1mV vs. 15mV), and extended operating temperature range (-40°C to 125°C). These parts maintain 8-SOIC or 8-uMAX/uSOP package compatibility and are available in high quantities (5,400 and 2,400 units respectively).

MAX989ESA+T provides CMOS output with push-pull, rail-to-rail, and TTL compatibility in 8-SOIC package, with faster propagation delay (450ns) and lower input offset voltage (5mV). Inventory availability is substantial at 17,129 units.

MAX991ESA+ offers similar CMOS output characteristics with even faster propagation delay (210ns) in 8-SOIC package, with 3,364 units in stock.

BU7232FVM-TR (Rohm Semiconductor) provides an alternative in 8-MSOP package with faster propagation delay (1.7µs) and lower input offset voltage (11mV), though supply voltage range is limited to 1.8V ~ 5.5V. Inventory: 3,204 units.

HA1631D01TEL-E (Renesas Electronics) offers open-drain and push-pull output options in 8-TSSOP package with superior input offset voltage (5mV) and comparable quiescent current (20µA). Inventory: 1,096 units.

All recommended substitutes maintain ROHS3 compliance and MSL Level 1 moisture sensitivity rating. Selection should be based on specific application requirements regarding supply voltage range, output current capability, propagation delay, and package footprint constraints.

Frequently Asked Questions (FAQ)

Q: Can LMC6762BIMX/NOPB be used as a direct replacement for LMC6762BIMX?

A: Yes. LMC6762BIMX/NOPB is a parametric equivalent with identical electrical specifications, output type (push-pull, rail-to-rail), supply voltage range (2.7V ~ 15V), and 8-SOIC package. The primary difference is product status: LMC6762BIMX/NOPB is active with 22,700 units available, while LMC6762BIMX is obsolete. No circuit modifications are required.

Q: What are the key differences between the LMC6762BIMX and MAX9032 series substitutes?

A: The MAX9032 series (MAX9032ASA+T, MAX9032AUA+) offers significantly faster propagation delay (228ns vs. 10µs), lower input offset voltage (1mV vs. 15mV), and extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C). However, supply voltage range is limited to 2.5V ~ 5.5V compared to the LMC6762BIMX range of 2.7V ~ 15V. These parts are suitable for applications operating within the 2.5V to 5.5V window where faster response time is beneficial.

Q: Are package changes acceptable when selecting a substitute?

A: Package changes are acceptable if the application PCB layout can accommodate the alternative footprint. LMC6762BIMX uses 8-SOIC (0.154", 3.90mm width). Substitutes are available in compatible 8-pin surface mount packages including 8-MSOP (0.110", 2.80mm width), 8-TSSOP (0.173", 4.40mm width), 8-uMAX/uSOP (0.118", 3.00mm width), and SOT-23-8. Footprint verification and PCB layout adjustment are required for non-SOIC packages.

Q: What is the significance of output type differences (push-pull vs. open-drain)?

A: Push-pull outputs actively drive both high and low logic states, suitable for direct logic interface applications. Open-drain outputs require external pull-up resistors and are used in applications requiring wired-OR logic or open-collector compatibility. The LMC6762BIMX features push-pull, rail-to-rail output. HA1631D01TEL-E offers both open-drain and push-pull options; verify output type compatibility with the application circuit before selection.

Q: How does supply voltage range affect substitute selection?

A: The LMC6762BIMX operates across 2.7V ~ 15V (single supply) or ±1.35V ~ ±7.5V (dual supply). Most active substitutes (MAX9022, MAX9032, MAX989, MAX991 series) are limited to 2.5V ~ 5.5V single supply. These substitutes are suitable only for applications operating within the 2.5V to 5.5V window. For applications requiring operation above 5.5V or below 2.5V, LMC6762BIMX/NOPB or BU7232FVM-TR must be selected.

Q: What compliance certifications apply to all substitute parts?

A: All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (unlimited) moisture sensitivity rating, matching the LMC6762BIMX specifications. All parts carry EAR99 ECCN classification and REACH Unaffected status. Compliance documentation is available from respective manufacturers.

Q: Which substitute offers the best performance improvement over LMC6762BIMX?

A: MAX9032ASA+T and MAX9032AUA+ provide the most significant performance improvements: propagation delay reduced from 10µs to 228ns (44x faster), input offset voltage reduced from 15mV to 1mV, and CMRR/PSRR improved to 100dB. These improvements are substantial for high-speed comparison applications. However, supply voltage range limitation (2.5V ~ 5.5V) must be verified against application requirements.

Q: Are there inventory considerations for long-term supply?

A: Yes. LMC6762BIMX is obsolete with limited remaining inventory (1,174 units). LMC6762BIMX/NOPB provides the most secure long-term supply with 22,700 units in stock. Among manufacturer-recommended alternatives, MAX9032ASA+T (5,400 units) and MAX989ESA+T (17,129 units) offer substantial inventory. For critical applications requiring extended production support, LMC6762BIMX/NOPB is the recommended selection.
