MAX913CSA Equivalent & Substitute Parts

Part Overview

The MAX913CSA is a single-channel comparator with latch functionality, manufactured by Analog Devices Inc./Maxim Integrated. It features complementary TTL output and operates across a 5V to 10V supply range. The device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. This reference provides direct equivalents and functional alternatives that maintain electrical and mechanical compatibility within the specified parameter envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX913CSA is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Supply voltage range: 5V ~ 10V (minimum requirement)
• Output type: Complementary, TTL
• Propagation delay: ≤14ns maximum
• Current output capability: ≥20mA typical
• Input offset voltage: ≤2mV @ ±5V
• Input bias current: ≤5µA @ ±5V

Mechanical Compatibility Requirements:

• Package: 8-SOIC (0.154", 3.90mm Width) or compatible surface-mount packages
• Mounting type: Surface Mount
• Pin count: 8 pins

Functional Requirements:

• Comparator with latch functionality or general-purpose comparator operation
• Single-channel configuration

Substitute parts are grouped into two categories:

1. Direct Equivalents - Identical part numbers with different packaging or compliance status (MAX913CSA+)
2. Functional Alternatives - Texas Instruments TL3116 series devices that meet or exceed electrical specifications within the allowed parameter envelope

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): MAX913CSA+ is the primary substitute. It maintains identical electrical specifications and 8-SOIC packaging while offering active product status and ROHS3 compliance. This part provides the most direct substitution path with no design modifications required.

For Extended Temperature Range Applications: TL3116IDR and TL3116ID support -40°C to 85°C operating temperature, compared to the MAX913CSA's 0°C to 70°C range. These parts are suitable for industrial and automotive applications requiring wider temperature operation. TL3116IDR is currently active, while TL3116ID is obsolete.

For RoHS3 Compliance Requirements: All Texas Instruments TL3116 variants (TL3116CD, TL3116CDR, TL3116CPWR, TL3116ID, TL3116IDR) and MAX913CSA+ meet ROHS3 compliance. The original MAX913CSA does not comply with RoHS regulations.

For Package Flexibility: TL3116CPWR offers 8-TSSOP packaging as an alternative to 8-SOIC, suitable for space-constrained designs. This variant requires PCB layout modification but maintains electrical compatibility.

For Active Product Status: MAX913CSA+ and TL3116IDR are the only active products in this substitution group, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I use TL3116 series parts as direct replacements for MAX913CSA? A: Yes, within electrical parameter limits. TL3116 devices meet or exceed the MAX913CSA's electrical specifications. However, verify operating temperature requirements: TL3116CD/CDR/CPWR operate 0°C to 70°C (matching MAX913CSA), while TL3116ID/IDR extend to -40°C to 85°C. All maintain 8-SOIC packaging except TL3116CPWR (8-TSSOP).

Q: What is the difference between MAX913CSA and MAX913CSA+? A: Both parts are electrically identical with 2mV input offset and 14ns propagation delay. The primary differences are packaging format (Tube for MAX913CSA+) and compliance status (MAX913CSA+ is ROHS3 compliant and active, while MAX913CSA is obsolete and non-compliant).

Q: Are there supply voltage differences between MAX913CSA and TL3116 variants? A: The MAX913CSA operates at 5V ~ 10V. TL3116 series parts support both 5V ~ 10V and ±2.5V ~ 5V supply ranges, providing greater flexibility for dual-supply applications.

Q: What is the impact of higher quiescent current in TL3116 parts? A: TL3116 variants draw 14.7mA to 15mA quiescent current compared to MAX913CSA's 10mA maximum. For battery-powered or low-power applications, this 4.7mA to 5mA increase may require power budget recalculation.

Q: Can I use TL3116CPWR in place of 8-SOIC packaged parts? A: TL3116CPWR uses 8-TSSOP packaging instead of 8-SOIC. While electrically compatible, this requires PCB redesign due to different pin pitch and footprint. Use only if layout modifications are acceptable.

Q: Which substitute offers the best long-term availability? A: TL3116IDR (Active status, Texas Instruments) and MAX913CSA+ (Active status, Analog Devices) are the only currently active products. Both ensure continued supply and support.

Q: Do all substitutes maintain the same propagation delay? A: No. MAX913CSA and MAX913CSA+ specify 14ns maximum propagation delay. All TL3116 variants specify 12ns maximum, which is faster and suitable for timing-critical applications.

Q: Are there input bias current differences I should consider? A: Yes. MAX913CSA specifies 5µA maximum input bias current, while all TL3116 variants specify 1.1µA maximum. Lower bias current in TL3116 parts reduces input loading effects and may improve circuit performance in high-impedance applications.
