DESCRIPTION/ORDERING
INFORMATION
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 V.11.
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.
