DS1265AB-70IND NVSRAM Memory IC Equivalent & Substitute Parts

Part Overview

The DS1265AB-70IND is a Non-Volatile SRAM (NVSRAM) memory integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This 8Mbit parallel memory device operates at 70 ns access time and is housed in a 36-EDIP package. The part is currently classified as obsolete, making identification of compatible substitute components essential for system maintenance, repair, and legacy product support. The DS1265AB-70IND remains in limited inventory (3936 pcs), but its obsolete status necessitates evaluation of active alternative components that maintain electrical and mechanical compatibility.

Engineering Selection Recommendations

The DS1265AB-70IND+ is a direct functional equivalent to the DS1265AB-70IND. Both components share identical electrical specifications, memory capacity, access timing, voltage requirements, and thermal operating range. The primary distinction is product lifecycle status: the DS1265AB-70IND is obsolete while the DS1265AB-70IND+ maintains active production status.

For new designs or long-term system support, the DS1265AB-70IND+ is the appropriate selection due to its active product status and ROHS3 compliance. The DS1265AB-70IND remains suitable for immediate replacement applications where existing inventory is available and RoHS non-compliance is acceptable within the application context.

Both components are supplied in 36-EDIP through-hole packages with identical mechanical footprints, enabling direct board-level substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can DS1265AB-70IND+ be used as a direct replacement for DS1265AB-70IND?

A: Yes. The DS1265AB-70IND+ is electrically and mechanically identical to the DS1265AB-70IND. Both components feature 8Mbit NVSRAM capacity, 70 ns access time, parallel interface, 4.75V ~ 5.25V supply voltage, -40°C ~ 85°C operating temperature range, and 36-EDIP package configuration. Direct substitution is possible without circuit modification.

Q: What is the difference between DS1265AB-70IND and DS1265AB-70IND+?

A: The primary differences are product status and compliance certification. The DS1265AB-70IND is obsolete and RoHS non-compliant. The DS1265AB-70IND+ is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these components?

A: No. Both components use the 36-EDIP package with identical mechanical dimensions (0.610", 15.49mm) and through-hole mounting configuration. Pinout and footprint compatibility is complete.

Q: Which component should be selected for new designs?

A: The DS1265AB-70IND+ should be selected for new designs due to its active product status and ROHS3 compliance. The DS1265AB-70IND is suitable only for replacement of existing systems where the obsolete component is already in use.

Q: What is the supply voltage compatibility range for both components?

A: Both the DS1265AB-70IND and DS1265AB-70IND+ operate within the 4.75V ~ 5.25V supply voltage range. System power supply design must maintain voltage within this specification for proper component operation.

Q: Are both components suitable for -40°C to 85°C temperature environments?

A: Yes. Both components are rated for -40°C ~ 85°C operating temperature range (TA). System thermal design must maintain component temperature within this specification.
