MAX764CSA-T Equivalent & Substitute Parts

Part Overview

The MAX764CSA-T is a Buck-Boost Switching Regulator IC manufactured by Analog Devices Inc./Maxim Integrated, designed for negative adjustable output voltage applications. This component generates a negative output voltage (-1V to -16V) from a positive input supply (3V to 16V), delivering up to 260mA output current in an 8-SOIC surface mount package. The MAX764CSA-T is classified as obsolete, making identification of equivalent substitute parts essential for ongoing production support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX764CSA-T are identified based on strict electrical and mechanical parameter matching within the power management IC category. The critical parameters determining substitution eligibility are:

• Buck-Boost topology with negative output configuration
• Input voltage range: 3V to 16V
• Output voltage range: -1V to -16V
• Output current capability: 260mA
• Switching frequency: 300kHz
• Package type: 8-SOIC surface mount
• Operating temperature range: 0°C to 70°C

The MAX764CSA+T qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction between the main part and substitute is product status and packaging designation suffix.

Parameter Comparison

Engineering Selection Recommendations

The MAX764CSA+T is the recommended substitute for the obsolete MAX764CSA-T. Both components share identical electrical specifications and mechanical packaging, ensuring direct functional equivalence. The MAX764CSA+T maintains active product status with Analog Devices Inc./Maxim Integrated, providing ongoing availability and manufacturing support. Both parts comply with ROHS3 requirements and carry identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001). The packaging designation suffix difference (-T versus +T) reflects manufacturing or distribution variations but does not affect electrical or mechanical compatibility. Selection of the MAX764CSA+T eliminates obsolescence risk while maintaining full design compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MAX764CSA+T be used as a direct replacement for the MAX764CSA-T?

A: Yes. Both parts are electrically and mechanically identical, with matching input/output voltage ranges, current ratings, switching frequency, package type, and operating temperature specifications. The primary difference is product status: MAX764CSA-T is obsolete while MAX764CSA+T is active.

Q: What does the packaging suffix difference (-T versus +T) indicate?

A: The suffix designates packaging or distribution variants. This difference does not affect electrical performance, mechanical fit, or functional compatibility in circuit applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance status, REACH classification, ECCN designation, and HTSUS codes.

Q: What are the critical parameters for substitution in negative buck-boost regulator applications?

A: Critical parameters include output voltage polarity (negative), input voltage range (3V to 16V), output voltage range (-1V to -16V), output current capability (260mA), switching frequency (300kHz), and package type (8-SOIC surface mount).

Q: Is the 8-SOIC package footprint identical between both parts?

A: Yes. Both parts use the 8-SOIC package with 0.154" width (3.90mm), ensuring identical PCB footprint and mounting compatibility.
