DESCRIPTION
The SN65C1167, SN75C1167, SN65C1168, and SN75C1168 dual drivers and receivers are integrated circuits
designed for balanced transmission lines. The devices meet TIA/EIA-422-B and ITU recommendation V.11.
The SN65C1167 and SN75C1167 combine dual 3-state dierential line drivers and 3-state dierential line
receivers, both of which operate from a single 5-V power supply. The driver and receiver have active-high and
active-low enables, respectively, which can be connected together externally to function as direction control. The
SN65C1168 and SN75C1168 drivers have individual active-high enables.
