Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM360N/NOPB is determined by the following critical parameters:

• Package compatibility: 8-DIP (0.300", 7.62mm) form factor with through-hole mounting
• Functional type: Single differential comparator element
• Output configuration: Complementary output stage
• Supply voltage range: Compatibility with ±4.5V ~ 6.5V dual supply operation
• Input offset voltage: Maximum 5mV specification
• Input bias current: Maximum 20µA specification
• Propagation delay: Maximum 130ns specification
• Operating temperature range: Minimum coverage of 0°C ~ 70°C
• Regulatory compliance: ROHS3 compliance required

The MAX9691EPA+ qualifies as a substitute based on matching package geometry, single-element differential comparator architecture, complementary output stage, and regulatory compliance certifications. Both devices utilize 8-PDIP packaging suitable for through-hole PCB assembly.

Parameter Comparison

Engineering Selection Recommendations

The MAX9691EPA+ is available as an active product from Analog Devices Inc./Maxim Integrated, addressing the obsolescence status of the LM360N/NOPB. Both devices maintain ROHS3 compliance and identical 8-DIP package geometry, enabling direct PCB footprint compatibility.

The MAX9691EPA+ demonstrates superior propagation delay performance (1.8ns versus 130ns) and extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C). Input offset voltage and input bias current specifications remain within acceptable tolerance bands for direct substitution. The latch functionality integrated into the MAX9691EPA+ provides additional signal conditioning capability without compromising baseline comparator operation.

Selection of the MAX9691EPA+ ensures continued component availability, regulatory compliance maintenance, and access to active manufacturer technical support.

Frequently Asked Questions (FAQ)

Q: Can the MAX9691EPA+ be used as a direct pin-for-pin replacement for the LM360N/NOPB?

A: Yes. Both devices utilize identical 8-DIP package geometry with matching pinout configuration for through-hole mounting. No PCB layout modifications are required for physical substitution.

Q: What are the key electrical differences between these devices?

A: The MAX9691EPA+ features significantly faster propagation delay (1.8ns versus 130ns), higher typical output current (50mA versus 20mA), and an integrated latch function. Input offset voltage and bias current specifications remain comparable. Output logic family differs (ECL versus TTL), which may require interface circuit evaluation in specific applications.

Q: Does the extended operating temperature range of the MAX9691EPA+ affect compatibility?

A: The MAX9691EPA+ operating range (-40°C ~ 85°C) encompasses the LM360N/NOPB specification (0°C ~ 70°C). This extended range provides additional design margin and does not create compatibility issues for applications within the original temperature specification.

Q: Are there any supply voltage compatibility concerns?

A: The LM360N/NOPB specifies ±4.5V ~ 6.5V dual supply operation. The MAX9691EPA+ supply voltage specification is not provided in the available data. Circuit design review is necessary to confirm supply voltage compatibility for specific applications.

Q: What regulatory certifications apply to both devices?

A: Both the LM360N/NOPB and MAX9691EPA+ maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications.
