Memory IC Procurement Notes

Verify the specific IND suffix confirms the extended industrial temperature range requirement. Confirm the AB designation matches the tighter voltage tolerance specifications needed for the target circuit design. Ensure compatibility with the 32-pin EDIP footprint during board layout validation.

Memory IC Selection Notes

Select this part when nonvolatile storage is required without external battery management circuits. The AB variant provides stricter voltage limits compared to the Y series. Verify that the 70ns speed meets system timing requirements. Consider the PowerCap module alternative if surface-mount assembly is preferred over through-hole technology.

Memory IC Part Context

This device belongs to the DS1250 family of nonvolatile SRAMs manufactured by Analog Devices Inc./Maxim Integrated. It integrates SRAM memory, control logic, and a lithium battery into a single package. The IND suffix indicates compliance with industrial environmental standards.
