I'm afraid it's a flash memory for the aerospace industry. Sorry, no data sheet.

221-241 Flash memory #0321 - 221-241 in Other Electronic Components

The number reminds me of old Radio Spares catalogue numbers.

Or it is the Zenith part number for whatever it is.

You may be confused by that generic image. There are 4 Google references to 221-241; 3 of them to a
Siemens DIP 8 flash memorywhich must be > 14yrs ago, since Siemens semi. became Infineon in 1999.

In the absence of any other DIP 8 references, and that this Siemens component is still on US aerospace
databases, I think you will have to accept that your pic. and description match is the only likely one.
