The 300 mV receiver hysteresis helps clean up noisy lines.
If you have an existing BOM line that calls out this order code, you will need to source it from independent distribution or consider a pin-compatible replacement. The 16-TSSOP footprint and 2/2 driver/receiver count are common across the MAX3232 family, so a like-for-like swap is possible with a current-production sibling — verify the supply range and temperature grade against your design before committing the change.
The 16-TSSOP body is 4.40 mm wide with a 0.65 mm pitch — a standard fine-pitch SOIC footprint that reflows cleanly with a typical lead-free profile. The TSSOP has low thermal mass; a 260°C peak reflow with a gentle ramp-down will lift the part without lifting the pad. No moisture sensitivity level is listed, but a 24-hour bake at 125°C before rework is cheap insurance if the original reel has been open.
