Low Power Rs-485 / Rs-422 Differential Bus Transceiver - National Semiconductor

The LMS485E is a low power differential bus/line transceiver designed for high speed bidirectional data Communication on multipoint bus transmission lines. It is designed for balanced transmission lines. It meets ANSI Standards TIA/EIA RS422-B, TIA/EIA RS485-A and ITU recommendation and V.11 and X.27. The driver outputs and receiver inputs have 15kV ESD protection. The LMS485E combines a TRI- STATE differential Line Driver and differential input receiver, both of which operate from a single 5.0V power supply. The driver and receiver have an active high and active low, respectively, that CAN be externally connected to function as a direction control. The driver outputs and receiver inputs are internally connected to form a differential input/output (I/O) bus port that is designed to offer minimum loading to bus whenever the driver is disabled or when VCC = 0V. These ports feature wide positive and negative common mode voltage ranges, making the device suitable for multipoint applications in noisy environments. The LMS485E is avail- able in 8-Pin SOIC and 8-pin DIP packages. It is a drop-in replacement to Maxims MAX485E. By National Semiconductor Corporation
