The transceiver operates in one of three modes: Normal, Driver Disable or Shutdown. In the Normal mode, ICC is only 200A in the unloaded condition. In the Driver Disable mode, the charge pump is turned off, the driver outputs are forced into three-state, both receivers are kept active, and ICC drops to 35A. In the Shutdown mode, everything is turned off and ICC drops to 0.2A. The LTC1385 is fully compliant with all data rate and overvoltage EIA / TIA-562 specifications. The transceiver can operate up to 120kbaud with a 1000pF, 3k load. Both driver outputs and receiver inputs can be forced to 25V without damage, and can survive multiple 10kV ESD strikes. |
