Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX912ESE is determined by strict equivalence across the following critical parameters:

• Functional Architecture: Dual comparator with integrated latch
• Output Configuration: Complementary TTL logic
• Electrical Performance: Input offset voltage (2mV max), input bias current (5µA max), output current (20mA typical), quiescent current (10mA max), CMRR/PSRR specifications (110dB/100dB), and propagation delay (14ns max)
• Supply Voltage Range: 5V to 10V operation
• Package Compatibility: 16-SOIC surface mount form factor with 0.154" (3.90mm) width
• Temperature Range: -40°C to 85°C operating window

The MAX912ESE+ meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAX912ESE+ is the direct substitute for the MAX912ESE. Both devices are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications and package geometry. The primary distinction is product lifecycle status: the MAX912ESE is obsolete, while the MAX912ESE+ is active production.

For new designs or production continuity, the MAX912ESE+ is the appropriate selection. The MAX912ESE+ additionally provides ROHS3 compliance, meeting modern environmental and regulatory requirements that the original MAX912ESE does not satisfy. Both devices maintain identical performance characteristics across all specified electrical parameters, ensuring direct functional interchangeability in 16-SOIC surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can the MAX912ESE+ be used as a direct replacement for the MAX912ESE?

A: Yes. The MAX912ESE+ is electrically and mechanically identical to the MAX912ESE. Both devices feature the same dual comparator with latch architecture, complementary TTL output configuration, 5V to 10V supply range, and 16-SOIC package geometry. The primary difference is product status and RoHS compliance.

Q: What is the significance of the product status difference?

A: The MAX912ESE is classified as obsolete, indicating discontinued manufacturing and limited availability. The MAX912ESE+ is in active production, ensuring reliable supply for current and future applications. For production designs, the active status of the MAX912ESE+ provides supply chain stability.

Q: Are there any electrical performance differences between these parts?

A: No. Both the MAX912ESE and MAX912ESE+ maintain identical specifications for input offset voltage, input bias current, output current, quiescent current, CMRR, PSRR, propagation delay, and operating temperature range.

Q: Does the RoHS compliance difference affect circuit performance?

A: RoHS compliance relates to material composition and environmental standards, not electrical performance. Both devices operate identically within specified electrical parameters. The MAX912ESE+ ROHS3 compliance satisfies modern regulatory requirements for manufacturing and environmental responsibility.

Q: Are the packages physically identical?

A: Yes. Both devices use the 16-SOIC package with 0.154" (3.90mm) width. PCB footprints and mounting procedures are identical, enabling direct board-level substitution without layout modifications.
