MAX764EPA Equivalent & Substitute Parts

Part Overview

The MAX764EPA is a buck-boost switching regulator IC from Analog Devices Inc./Maxim Integrated, designed to generate negative adjustable or fixed output voltages (-1V to -5V configurations). This device operates as a step-up/step-down converter with a single negative output, capable of delivering 260mA across an input voltage range of 3V to 16V. The MAX764EPA is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX764EPA is determined by strict equivalence across the following critical parameters:

• Identical buck-boost topology with negative output configuration
• Matching input voltage range (3V to 16V minimum and maximum)
• Equivalent or greater output current capability (260mA)
• Identical switching frequency (300kHz)
• Same package and pinout (8-DIP, 0.300" spacing)
• Identical output voltage range (-1V to -16V)
• Matching operating temperature range (-40°C to 85°C)

The MAX764EPA+ qualifies as a direct substitute based on full parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX764EPA+ is the direct functional equivalent of the MAX764EPA. Both devices share identical electrical specifications, package configuration, and performance characteristics. The primary distinction is product status: the MAX764EPA is obsolete, while the MAX764EPA+ maintains active production status.

For new designs and ongoing system support, the MAX764EPA+ is the appropriate selection. This substitute provides continuity of supply and maintains full electrical and mechanical compatibility with existing MAX764EPA implementations. The MAX764EPA+ additionally offers ROHS3 compliance, aligning with current environmental and regulatory standards, whereas the original MAX764EPA is RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q: Can MAX764EPA+ be used as a direct replacement for MAX764EPA in existing designs?

A: Yes. The MAX764EPA+ is electrically and mechanically identical to the MAX764EPA. Both devices feature the same 8-DIP package, pinout, input/output voltage ranges, output current capability, and switching frequency. Direct substitution is possible without circuit modification.

Q: What is the difference between MAX764EPA and MAX764EPA+?

A: The devices are functionally equivalent. The primary differences are product status (MAX764EPA is obsolete; MAX764EPA+ is active) and RoHS compliance (MAX764EPA is non-compliant; MAX764EPA+ is ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use the same 8-DIP (0.300", 7.62mm) through-hole package. The MAX764EPA is supplied in standard packaging, while the MAX764EPA+ is supplied in tube packaging. This does not affect electrical performance or board-level compatibility.

Q: What output voltage configurations are available?

A: The MAX764EPA and MAX764EPA+ support negative output voltage generation across the range of -1V to -16V. Standard fixed configurations include -1V and -5V outputs, with adjustable output capability through external resistor networks.

Q: Is the MAX764EPA+ suitable for new product designs?

A: Yes. The MAX764EPA+ is the recommended choice for new designs. It maintains active production status, ensuring long-term availability, and meets current RoHS3 compliance requirements.
