Data rate — 250 kbps practical ceiling
The 250 kbps data rate is enough for most legacy serial protocols. If your application needs higher speed, this part won't close the timing.

Both are 2/2 RS-232 transceivers in 20-SSOP, but the MAX3224EAP+ runs at 250 kbps while the MAX3223EAP+ is limited to 120 kbps. Check the data rate requirement — if 250 kbps is acceptable, the pinout and footprint are compatible for a drop-in swap.
