ep610 partnumber decode

I pulled up an old datasheet, and it didn't have the full part numbering scheme, but here's what I gleamed from ArrowNAC website.

[EP610] [l] [-xx] [N]

^ Device family

^ Alternate specs in data sheet. (Maybe a die difference??)

^ PLCC Package L= PLCC P= PDIP D= CDIP

^ Industrial Temp Grade C= Commercial

^ speed grade

^ ROHS compliant if N is present at end of part number

Sorry the spacing didn't work correctly, with the post, every new line starting with a ^ should have lined up with the field in the part number.

Hope this helps..

The first "I" is confusing. It seems to drive to an industrial grade temp to meet the different parametric values. A non first "I" part, but with the second "I", is an idustrial part that has the basic EP610 parametric values, see page 432 of spec. Does that make sense?

I Agree the first I is confusion.

My only thought is they had a major customer at one point that needed industrial temp, but they couldn't quite reach the standard specs at that point, so they de-rated the specs where they couldn't meet it, and the customer signed off on it.

I know back in the late 90's when I worked for a IC house, we had a special military cycle on one product, where they were using the parts beyond are standard specs, and had us datalog and serialize each part at all three temps so they could pick and choose the ones they thought would work in their system.
