Interesting. It could be a date code?

When repairing a TU60 drive that had faulty
DEC8881 I replaced them with
DM7439. They were $2.76 each when buying 25 pieces. The original faulty
chips were marked 7439 on the backside.
By way of confirmation, I have a bunch of (I think Signetics) 8881 chips marked 7439 on
the bottom as well.
