LMC6762BIM/NOPB Equivalent & Substitute Parts

Part Overview

The LMC6762BIM/NOPB is a general-purpose dual comparator manufactured by Texas Instruments, featuring push-pull, rail-to-rail output architecture 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), with a maximum input offset voltage of 15mV at 5V and typical output current of 30mA.

The LMC6762BIM/NOPB is currently in Last Time Buy status with 1,345 units in stock. Due to this product status, equivalent and substitute parts are necessary for long-term design continuity and procurement planning. Substitute devices must maintain functional compatibility across critical electrical parameters including supply voltage range, input offset voltage, output type, and package form factor.

Substitute Part Grouping Explanation

Substitution eligibility for the LMC6762BIM/NOPB is determined by the following critical parameters:

Primary Compatibility Criteria:

Output type must be Push-Pull or Push-Pull with Rail-to-Rail capability
Supply voltage range must overlap with or exceed 2.7V ~ 15V (single supply)
Package must be surface mount 8-pin configuration (SOIC, MSOP, UFLGA, or equivalent)
Input offset voltage specification must not exceed 15mV at rated supply voltage
Operating temperature range must include -40°C minimum

Secondary Compatibility Factors:

Quiescent current and output current specifications should align with application requirements
CMRR and PSRR performance should meet or exceed 75dB and 80dB respectively
Propagation delay should not significantly exceed 10µs for timing-critical applications
RoHS3 compliance and MSL rating should match or exceed the original specification

Substitute parts are grouped into two categories: direct replacements (identical electrical performance and package) and functional equivalents (compatible electrical performance with alternative packaging).

Engineering Selection Recommendations

Direct Replacement (Identical Electrical and Package Specifications):

LMC6762BIMX/NOPB is the primary direct replacement for LMC6762BIM/NOPB. Both devices are manufactured by Texas Instruments with identical electrical specifications, supply voltage range, and 8-SOIC package configuration. The primary difference is product status: LMC6762BIMX/NOPB is in Active status with 22,700 units in stock, compared to the Last Time Buy status of the original part. This substitution requires no circuit modifications and maintains full functional compatibility.

Compatible Substitutes (Functional Equivalence with Design Considerations):

MAX9032ASA+ and MAX9032ASA+T (Analog Devices/Maxim) provide superior electrical performance with lower input offset voltage (1mV vs. 15mV), higher CMRR/PSRR (100dB), and significantly faster propagation delay (228ns vs. 10µs). These devices maintain Push-Pull, Rail-to-Rail output architecture and 8-SOIC packaging. However, the supply voltage range is restricted to 2.5V ~ 5.5V (single supply only), which may limit applications requiring higher supply voltages or dual supply operation.

MAX989EUA+T (Analog Devices/Maxim) offers enhanced performance characteristics including CMOS output architecture, faster propagation delay (450ns), and lower quiescent current (24µA). The 8-TSSOP/MSOP package requires PCB layout modifications but maintains functional compatibility for applications operating within the 2.5V ~ 5.5V supply range.

BU7232F-E2 and BU7232SFVM-TR (Rohm Semiconductor) provide active-status alternatives with lower input offset voltage (11mV) and faster propagation delay (1.7µs). Supply voltage range is restricted to 1.8V ~ 5.5V. BU7232F-E2 uses 8-SOIC packaging (direct footprint compatibility), while BU7232SFVM-TR uses 8-MSOP packaging (requires layout modification).

AZV3002RL-7 (Diodes Incorporated) operates within a narrower supply voltage range (1.6V ~ 5.5V) and features the smallest package footprint (8-UFLGA). This device is suitable only for applications with supply voltages not exceeding 5.5V and where compact packaging is prioritized.

HA1631D01MMEL-E (Renesas Electronics) features Open-Drain and Push-Pull output options with the lowest input offset voltage (5mV) and operates within 1.8V ~ 5.5V supply range. The 8-TSSOP/MSOP package requires layout modification. This device is suitable for applications requiring open-drain output capability.

All substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can LMC6762BIMX/NOPB be used as a direct replacement for LMC6762BIM/NOPB?

A: Yes. LMC6762BIMX/NOPB is the direct equivalent with identical electrical specifications, supply voltage range (2.7V ~ 15V / ±1.35V ~ 7.5V), and 8-SOIC package. The only difference is product status (Active vs. Last Time Buy) and packaging format (Cut Tape & Digi-Reel vs. Tube). No circuit modifications are required.

Q: What are the key limitations when substituting with MAX9032ASA+ or MAX9022ASA+?

A: Both Maxim devices restrict supply voltage to 2.5V ~ 5.5V (single supply only), eliminating dual supply operation capability and applications requiring supply voltages above 5.5V. Applications operating within this voltage range benefit from superior input offset voltage (1mV) and faster propagation delay (228ns for MAX9032, 8µs for MAX9022).

Q: Are package changes required for any substitute parts?

A: LMC6762BIMX/NOPB, BU7232F-E2, and MAX9032ASA+ maintain 8-SOIC packaging and require no PCB layout modifications. BU7232SFVM-TR, MAX9022AUA+T, MAX989EUA+T, and HA1631D01MMEL-E use 8-MSOP or 8-TSSOP packages, requiring PCB footprint redesign. AZV3002RL-7 uses 8-UFLGA packaging, requiring significant layout modification.

Q: Which substitute part offers the best performance improvement?

A: MAX9032ASA+ provides the most significant performance enhancement with 1mV input offset voltage (versus 15mV), 100dB CMRR/PSRR (versus 75dB/80dB), and 228ns propagation delay (versus 10µs). However, this device is limited to 2.5V ~ 5.5V supply voltage range and requires verification that application requirements do not exceed this specification.

Q: Can substitutes with narrower supply voltage ranges be used in applications designed for 2.7V ~ 15V operation?

A: No. Substitutes with restricted supply voltage ranges (such as MAX9022, MAX9032, BU7232, AZV3002, and HA1631) are suitable only for applications operating within their specified voltage limits. Applications requiring operation above 5.5V or dual supply operation must use LMC6762BIMX/NOPB or equivalent devices with matching supply voltage specifications.

Q: What is the significance of output type differences (Push-Pull vs. CMOS vs. Open-Drain)?

A: Output type determines load driving capability and circuit interface requirements. Push-Pull and CMOS outputs can source and sink current, suitable for direct logic interface. Open-Drain outputs require external pull-up resistors. HA1631D01MMEL-E offers both Open-Drain and Push-Pull options, providing flexibility for applications requiring open-drain functionality.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing processes and storage requirements equivalent to the original LMC6762BIM/NOPB specification.
