DESCRIPTION
Exar's SP385E is an enhanced version of the SP200 family of RS-232 line drivers/receivers. The
SP385E offers +3.3V operation for EIA-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.
