The SN65C1167E and SN65C1168E consist
of dual drivers and dual receivers with ±15kV ESD (Human Body Model [HBM]) and ±8-kV
ESD (IEC61000-4-2 Air-Gap Discharge and Contact Discharge) for RS-422 bus pins. The
devices meet the requirements of TIA/EIA-422-B and ITU recommendation V.11.The SN65C1167E combines dual 3-state
differential line drivers and 3-state differential line receivers, both of which
operate from a single 5V 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.SN65C1168E drivers have individual
active-high enables.
