MaxLinear | SP336EEY-L/TR

The SP336 is a programmable RS-232 and/or RS-485/RS-422 transceivers. The SP336 contains four drivers and four receivers when selected in RS-232 mode; and two drivers and two receivers when selected in RS-485 mode.  In addition, it may be configured for RS-232 and RS-485/RS-422 mix mode configuration.

The RS-232 transceivers can typically operate at 250 kbps or 1Mbps while adhering to the RS-232 specifications. The RS-485/RS-422 transceivers can operate at 250 kbps and 10 Mbps while adhering to the RS-485/RS-422 specifications. The slew rate control pin minimizes problems with reflections on long and un-terminated cables. The RS-485/422 and RS-232 drivers and receivers can be disabled (High-Z output) by the three mode select pins.
