It is designed for balanced transmission lines and meets or exceeds ANSI TIA/EIA485-A and ISO 8482:1993, with the exception that the thermal shutdown is removed. This differential bus transceiver is a monolithic integrated circuit designed for bidirectional data communication on multipoint bustransmission lines. The driver and receiver have active-high and active-low enables, respectively, that can be externally connected together to function as direction control. The driver differential outputs and receiver differential inputs connect internally to form a differential input/ output (I/O) bus port that is designed to offer minimum loading to the bus when the driver is disabled or VCC = 0. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
