SN75C1168PWR Datasheet

RS-422 Interface IC


The SN75C1168PWR 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 SN75C1168PWR combine 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. The SN75C1168PWR drivers have individual active-high enables.
