 Both the 1702 and 1701 were the same size. There were
originally 4 parts; 1601, 1602, 1701 and 1702.
I forget which was which but I think it was that the
160x were syncronous bus and the 1x01's were open collector
as compared to 1x02's that were 3state. If anyone
cares, I can look it up in my doc's to get it right.
 By the time the 1702A's came out, I don't think anyone
saw the others.
