I'm working on a controller to drive some long >1m bidirectional
lines that require 220/330 termination and 48 ma. drive current
capability. For sake of argument, call them SCSI-1 SE (but they're
not SCSI (or HPIB)).
I'm finding that my choices are pretty limited. I could use a
74F621, 74FCT621 (CMOS) or a good old 75160. All appear to be within
the same approximate price range.
Can anyone make any recommendations?
Thanks,
Chuck
