The SN65C1167E and SN65C1168E consist of dual drivers and dual receivers with ±15-kV 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
The SN65C1167E combines dual 3-state differential line drivers and 3-state differential
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.
SN65C1168E drivers have individual active-high enables.
