SP385E is an enhanced version of the SP200 family of RS232 line drivers/receivers. The SP385E offers +3.3V operation for EIS-562 and EIA-232 applications. The SP385E features offered maintains the same performance features offered in its predecessors. The SP385E is available in plastic SOIC or SSOP packages operating over the commercial and industrial temperature ranges. The SP385E is pin compatible to the LTC1385 EIA-562 transceiver with the exception that the drivers are disabled with the ON/OFF pin.

For RS-232 it is 50 feet (15 meters), or the cable length equal to a capacitance of 2500 pF, at a maximum transmission rate of 19.2kbps. When we reduce the baud rate, it allows for longer cable length. For Example:
Baud Rate (bps) | Maximum RS-232 Cable Length (ft) |
19200 | 50 |
9600 | 500 |
4800 | 1000 |
2400 | 3000 |
