Receiver hysteresis is 100 mV, which provides noise immunity on the RS232 line side. That matters in industrial environments where long cables pick up coupled noise from motors or switching supplies. The hysteresis prevents chatter at the logic output when the differential signal is marginal.
Housed in a 20-SSOP (5.30 mm wide body), the part is a surface-mount device suited for automated assembly.
For a BOM freeze or a new design, this part is still a safe selection.
