MAX9024ASD Equivalent & Substitute Parts

Part Overview

The MAX9024ASD is a general-purpose CMOS comparator with rail-to-rail and TTL output capabilities, housed in a 14-SOIC surface mount package. This device is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The MAX9024ASD operates across a supply voltage range of 2.5V to 5.5V (single supply) or ±1.25V to ±2.75V (dual supply), with low input offset voltage and minimal quiescent current consumption.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX9024ASD is determined by the following critical parameters:

Functional Equivalence Criteria:

• Four independent comparator elements
• CMOS output architecture with rail-to-rail capability
• 14-SOIC surface mount package
• ROHS3 compliance and MSL-1 rating
• Operating temperature range compatibility (-40°C to 125°C preferred for industrial applications)

Electrical Compatibility Criteria:

• Supply voltage range must encompass or exceed 2.5V ~ 5.5V single supply operation
• Input offset voltage and input bias current specifications must support precision measurement applications
• Quiescent current and propagation delay characteristics must align with power budget and timing requirements

The substitute parts identified—MAX9024ASD+, TLV3704CD, TLV3704ID, and TLV3704IDR—share the same package footprint, element count, and core functional architecture. Variations exist in supply voltage range, input offset specifications, and product status, which determine suitability for specific application contexts.

Engineering Selection Recommendations

MAX9024ASD+ (Direct Manufacturer Upgrade) The MAX9024ASD+ is the primary substitute, offering identical electrical specifications to the original MAX9024ASD while maintaining active product status. This part is manufactured by the same supplier (Analog Devices Inc./Maxim Integrated) and provides direct functional replacement with no design modifications required. The transition from obsolete to active status ensures long-term availability and supply chain stability.

TLV3704ID (Extended Temperature Range Alternative) The TLV3704ID from Texas Instruments provides extended operating temperature coverage (-40°C to 125°C), matching the original device's temperature range. This part supports higher supply voltages (2.7V ~ 16V) and exhibits superior PSRR performance (105dB vs. 80dB). The TLV3704ID is suitable for applications requiring broader voltage operation or enhanced power supply rejection. Product status is Last Time Buy, indicating limited future availability.

TLV3704IDR (Extended Temperature Range, Cut Tape Packaging) The TLV3704IDR is functionally identical to the TLV3704ID but supplied in cut tape packaging, offering higher inventory availability (7044 units in stock). This variant is appropriate for high-volume production environments where tape-and-reel format is preferred for automated assembly processes.

TLV3704CD (Commercial Temperature Range) The TLV3704CD operates across a commercial temperature range (0°C to 70°C), which is narrower than the original device. This part is suitable only for applications with restricted operating temperature requirements and is not recommended for industrial or extended-temperature applications. Product status is Last Time Buy.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MAX9024ASD with MAX9024ASD+ without PCB modifications? A: Yes. The MAX9024ASD+ is a direct substitute with identical electrical specifications and the same 14-SOIC package footprint. No design changes are required.

Q: What are the key differences between the MAX9024ASD and TLV3704 series? A: The TLV3704 series supports higher supply voltages (up to 16V vs. 5.5V), exhibits lower quiescent current (1µA vs. 5µA), and features enhanced PSRR performance (105dB vs. 80dB). However, input offset voltage is higher (5mV vs. 1mV), which may affect precision measurement applications.

Q: Which substitute is best for industrial applications requiring -40°C to 125°C operation? A: Both TLV3704ID and TLV3704IDR support the full industrial temperature range. The TLV3704IDR offers superior inventory availability in cut tape format for high-volume production.

Q: Is TLV3704CD suitable for my application? A: The TLV3704CD operates only across 0°C to 70°C, making it unsuitable for industrial or extended-temperature applications. Use TLV3704ID or TLV3704IDR for full temperature range coverage.

Q: What packaging options are available for the substitute parts? A: MAX9024ASD+ is supplied in tube packaging. TLV3704CD and TLV3704ID are available in tube format, while TLV3704IDR is supplied in cut tape (CT) format for automated assembly processes.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All identified substitutes—MAX9024ASD+, TLV3704CD, TLV3704ID, and TLV3704IDR—are ROHS3 compliant with MSL-1 moisture sensitivity rating.
