When I click on the photo, I can zoom in and see it clearly, but here are links where I bought:
I bought this chip from digi-key:
TI (Texas Instruments)
I bought this from Jameco:
The original called for a TL16C450, but is no longer available, and this chip is a suitable replacement.
Not sure if this helps but they are not programmable chips, pretty much a communications IC and a RS232 driver/level shifter.
