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.
