Electronic – Unknown “268” DIP-14 IC

dipidentificationintegrated-circuit

I have been going through a container of old electronics and discovered a set of ten DIP-14 ICs labelled "268." I have searched this number as well as the additional unique number on each chip, but have had no luck identifying them.

Does anyone in this community recognize this chip?
Might someone have a data-sheet on hand?

Thank you

This might be a TTL version of 74F286 9 bit parity checker (1987), but no guarantee: they might have just used the same number.

I suggested T74LS268B1 because it is a little-known SGS 74 series 268 about which I have no further information, but even that only because that I think that would be a pin-compatible part: with that '69-'70 date code, it won't be LS technology.
