Many manufacturers make DES chips.  One that comes to mind is American Micro
Devices, though I don't remember a part number off hand.  I can find out and
post it to the list.  I do remember reading the data sheet, and it looked
like a nice implementation.  If I'm not mistaken, Motorola makes one as well,
though it may have been obsoleted by improvements in speed.
