MAX913EUA-T Equivalent & Substitute Parts

Part Overview

The MAX913EUA-T is a single-channel comparator with integrated latch functionality, featuring complementary TTL outputs. Manufactured by Analog Devices Inc./Maxim Integrated, this 8-pin surface-mount device operates across a 5V to 10V supply range and is designed for general-purpose voltage comparison applications requiring latched output states.

The MAX913EUA-T is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support long-term production requirements for systems currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX913EUA-T are identified based on strict electrical and mechanical parameter alignment:

Parametric Equivalent Classification: Parts that maintain identical electrical specifications across all critical parameters including supply voltage range, input offset voltage, input bias current, output current, CMRR/PSRR performance, propagation delay, and operating temperature range. Parametric equivalents may differ in packaging format (tube vs. tape & reel) or product status (active vs. obsolete).

Manufacturer Recommended Classification: Parts that satisfy the core functional requirements of voltage comparison with latched output and TTL-compatible outputs, but may exhibit variations in secondary parameters such as input offset voltage tolerance, input bias current, quiescent current, or operating temperature range. These parts are recommended by the original manufacturer as functional alternatives.

Key Parameters Determining Substitutability:

• Single-channel comparator with latch functionality
• Complementary TTL output configuration
• Supply voltage range: 5V ~ 10V minimum overlap
• Input offset voltage: 3mV or better
• Propagation delay: 14ns or faster
• 8-pin surface-mount package compatibility
• Operating temperature range overlap with application requirements

Parameter Comparison

Engineering Selection Recommendations

MAX913EUA+T (Parametric Equivalent): This part is the primary substitute for the MAX913EUA-T. It maintains identical electrical specifications and package dimensions while offering active product status and higher inventory availability (2081 pcs vs. 971 pcs). The only difference is packaging format (tape & reel vs. tube). This part is suitable for direct replacement in all applications where the MAX913EUA-T was originally specified. ROHS3 compliance and unlimited moisture sensitivity level are maintained.

TL3116CD (Manufacturer Recommended Alternative): This Texas Instruments comparator provides functional equivalence with notable trade-offs. It delivers superior propagation delay performance (12ns vs. 14ns) and lower input bias current (1.1µA vs. 5µA). However, it operates across a different temperature range (0°C ~ 70°C vs. -40°C ~ 85°C), exhibits higher input offset voltage (3mV vs. 2mV), and requires a different package footprint (8-SOIC vs. 8-TSSOP/8-MSOP). The TL3116CD is classified as Last Time Buy, indicating limited future availability. This part is suitable only for applications where the narrower operating temperature range and different package dimensions are acceptable. ROHS3 compliance is maintained.

Product Status Considerations: The MAX913EUA+T is the recommended choice for new designs and ongoing production due to its active status and parametric equivalence. The TL3116CD should be evaluated only when supply constraints on the MAX913EUA+T exist and application requirements align with its narrower temperature range and different package specifications.

Frequently Asked Questions (FAQ)

Q: Can MAX913EUA+T be used as a direct replacement for MAX913EUA-T?

A: Yes. The MAX913EUA+T is a parametric equivalent with identical electrical specifications and package dimensions. The only difference is packaging format (tape & reel vs. tube). No circuit modifications are required.

Q: What are the key differences between MAX913EUA-T and TL3116CD?

A: The TL3116CD differs in four critical areas: (1) Operating temperature range is narrower (0°C ~ 70°C vs. -40°C ~ 85°C), (2) Input offset voltage is higher (3mV vs. 2mV), (3) Quiescent current is higher (14.7mA vs. 10mA), and (4) Package footprint is different (8-SOIC vs. 8-TSSOP/8-MSOP). The TL3116CD does offer faster propagation delay (12ns vs. 14ns) and lower input bias current (1.1µA vs. 5µA).

Q: Is the TL3116CD suitable for applications requiring -40°C operation?

A: No. The TL3116CD operates only from 0°C to 70°C. Applications requiring -40°C ~ 85°C operation must use the MAX913EUA-T or MAX913EUA+T.

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

A: These are different surface-mount package footprints. The 8-TSSOP/8-MSOP has a 0.118" (3.00mm) width, while the 8-SOIC has a 0.154" (3.90mm) width. PCB layout and footprint designs are not interchangeable. Verify PCB compatibility before substituting with TL3116CD.

Q: Why is MAX913EUA-T classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The MAX913EUA+T (active status) is the recommended replacement for ongoing supply and production support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both MAX913EUA+T and TL3116CD are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: Which substitute part should be selected for new designs?

A: The MAX913EUA+T is the recommended choice for new designs. It provides parametric equivalence, active product status, and superior inventory availability compared to the obsolete MAX913EUA-T.
