DESCRIPTION…

The Sipex SP385A is an enhanced version of the Sipex SP200 family of RS232 line drivers/

receivers. The SP385A offers +3.3V operation for EIA-562 and EIA-232 applications. The

SP385A maintains the same performance features offered in its predecessors. The SP385A is

available in plastic SOIC or SSOP packages operating over the commercial and industrial

temperature ranges. The SP385A is pin compatible to the LTC1385 EIA-562 transceiver, except

the drivers in the SP385A can only be disabled with the ON/OFF pin.
