... The ADM4851/ ADM4855 offer a higher limit on driver output slew rate, allowing data transmission rates up to 500 kbps. The driver slew rates of the ADM4852/ADM4856 and the ADM4853/ADM4857 are not limited, offering data transmission rates up to 2.5 Mbps and 10 Mbps, respectively. ...

... Note that only one driver should be enabled at a time, while many receivers can be enabled. SHUTDOWN MODE The ADM4850–ADM4853 have a low power shutdown mode, which is enabled by taking RE high and DE low. If shutdown mode is not used, the fact that DE is active high and RE is active low offers a convenient way of switching the device between transmit and receive by tying DE and RE together ...
