SN65C1168E数据手册集成电路（IC）的驱动器接收器收发器规格书PDF

描述 Description

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.

SN65C1168E drivers have individual active-high enables.
