RS-232 link for industrial serial ports
Obsolete — planning the replacement now
The MAX3222EIPW is listed as obsolete. For new designs or a BOM respin, the pin-compatible MAX3222EIPWR (the tape-and-reel variant of the same die) is a direct drop-in if you can still source it, but it shares the same underlying product status. The practical replacement path is the MAX3223 or MAX3225 family from TI, which offer similar 2/2 driver/receiver counts and 500 kbps data rates in the same 20-TSSOP footprint. Confirm the exact supply voltage and receiver hysteresis match your application before swapping.
