... Other protection features include thermal shutdown and a controlled maximum short-circuit current (50mA Max). Input resistance remains unpowered or disabled, thus allowing hot swapping with- out loading the data lines. The LTC1518/LTC1519 operate from a single 5V supply and draw 12mA of supply current ...

... Figure 5. Input Thevenin Equivalent W U Fail-Safe Features The LTC1518/LTC1519 have a fail-safe feature that guar- antees the output logic HIGH state when the inputs are either shorted or left open (note that when inputs are left open, any external large leakage current might override the fail-safe) ...

... Both of these fail-safe features will keep the receiver from outputting false data pulses under fault conditions. Single-Ended Applications Over short distances, the LTC1518/LTC1519 can be con- figured to receive single-ended data by tying one input to a fixed bias voltage and connecting the other input to the driver output ...
