This family of TRI-STATE bus transceivers offers extreme
versatility in bus organized data transmission systems. The
data bus may be unterminated, or terminated DC or AC, at
one or both ends. Drivers in the third (high impedance) state
load the data bus with a negligible leakage current. The
receiver input current is low allowing at least 100 driver/re-
ceiver pairs to utilize a single bus. The bus loading is un-

on the receiver also.
