Looking at the datasheet, the 7439 has the same pinout

an 8881. I'm convinced that this is at least as good a replacement as a
7401.
A quick search for DM7439 comes up with a datasheet for a 4x2-input OC
NAND with the same pinout as a 7401, but with 48 ma max output current.
There's an SN7439 as well.
Offhand, I'd say they were the same thing as the 8881.
